To all persons working at the laboratories of: Applied Physics Biomolecular and Organic Electronics Molecular Physics S-SENCE

PREFACE This handbook is intended to give an overview of the organization at Applied Physics, and it should also clarify some rules and routines regarding safety and practical laboratory work. It should be regarded as a complement to the general regulations that are listed in the department handbook: http://www.ifm.liu.se/intra/ The general rules for IFM also applies to the Division of Applied Physics if not otherwise stated. Anyone who is about to perform laboratory work at Applied Physics must first understand the relevant parts of this handbook. If there is anything that needs to be changed or updated, you shall contact Jeanette Nilsson. It is especially important that the information in this handbook is examined together with guests and students working in our laboratories. Supervisors and teachers are responsible for their students, master students and project workers. It is your responsibility to learn which regulations and laws that govern your work. Your responsibilities increase with your knowledge and experience! Stefan Klintström

SAFETY FIRST! The safety of yourself, your colleagues and our guests shall always be a primary concern. Bear in mind the interdisciplinary nature of Applied Physics. Your neighbor does not necessarily understand the danger that can be involved in your research. Most incidents with fretting compounds are actually caused by spill from co-workers. Please do not rush the laboratory work; too many accidents are caused by stress.

ORGANIZATION A large portion of the research at Applied Physics is interdisciplinary and staffs include engineers, physicists, chemists, biologists and others. Several projects are chosen in the areas between physics and chemistry, and physics and biology. Yet, the research is also indeed intra disciplinary, primarily within surface physics. Many projects are run in collaboration with other laboratories at IFM and with external collaborators. The SSF1-funded research programmes/graduate schools Biomimetic Materials Science (Biomics), Centre for Organic Electronics (COE) and Forum Scientium are also administered at Applied Physics. Applied Physics has some 60-70 employees divided into several research divisions/groups (organization chart below). The scientific branch runes by the management group and the research activities are supported by a number of technicians and administrators. Scientific Branch Applied Physics Management Group

WHO IS RESPONSIBLE? Laws and regulations The working environment in Sweden is carefully regulated in Arbetsmiljölagen and Arbetarskyddstyrelsens författningssamling, AFS. These are available at http://www.av.se and should be consulted if necessary. Local copies are also available in Technical Service supply in room M225.

Local information The employer, Linköping University, is always responsible for the working environment. The Rector of the University has delegated the responsibility at IFM to the Head of the Department. The Head of IFM has then delegated the responsibility for the working environment to the employer representatives in the management group at Applied Physics. Bo Thunér is a resource person for the infrastructure at all laboratories at Applied Physics except from Applied Optics and Division of Biotechnology. Furthermore, each individual research laboratory has personnel how is responsible for the research details, risk analysis and for the practical laboratory work. For sensitive equipment there may be appointed equipment responsible persons, indicated by a sign posted next to the instrument. There is an independent control of the working environment at Applied Physics performed by the representative for the working environment that is appointed by the employer representative and the Labour Union. At IFM there is also an engineer specialized in environmental issues, chemical waste, gas handling etc. She can always be contacted for support. Deficiencies in the working conditions in a research laboratory shall primarily be reported to the person who is responsible for that specific laboratory or to the representative for the working environment or alternatively to Lokala Samverkansgruppen, LSG.

RESEARCH DETAILS

SELECTED GENERAL RULES When something is not working If you identify errors that are related to ventilation, heating, electrical supply, cooling water, fume hoods, doors, etc., then please report to: The House Manager, Akademiska Hus, Bo Lefdén, 013-364545. Local representative at IFM, Bengt Andersson, 1285. Upon burglary or vandalism, call University Security officer 4087, 5888. All other errors at the laboratories shall be reported to Bo Thunér.

If an accident or incident occurs Injuries shall be reported as soon as possible on a special form “Anmälan om arbetsskada”. The form can be obtained from the staff intendant at IFM or from http://www.fk.se, and shall be filled in via collaboration between the injured person and the person who is employer representative for the specific laboratory. The representative for the working environment and the employer representative shall sign the form. The form shall be sent back to the staff intendant. Incidents that could have caused injury on personnel or serious economic damage shall be reported on yet another form “Anmälan om tillbud”. The form can be obtained from the staff intendant at IFM or from: http://www.ifm.liu.se/admin/am/ The procedure for this form is the same as for injuries.

Work alone You are not allowed to work alone after normal working hours (normal weekdays 8.00 to 18.00). Weekdays during summer and other holiday seasons are considered as after normal working hours. However, working alone is allowed if the working alone alarm system is used. Exceptions from using the alarm system could be a very short visit at the laboratory to check an instrument. The alarm units and instructions for how to use them are found in the IFM mailroom. Guests and students that work for a shorter period at IFM Applied Physics shall not work alone.

Children Children under the age of 12 do not have access to the laboratories, not even under supervision.

Smoking Smoking is prohibited in the entire building, as well for the balcony in Zenit. You are recommended to go outside the building.

LABORATORY RULES Before starting to work As a general rule, you shall always clear with the person who is responsible for a specific laboratory before you are allowed to work in that laboratory. Before starting to work in any laboratory, introduce yourself, your work and the potential dangers to your colleagues at the laboratory. Also have them to explain their work to you. Always make sure that you know where the emergency shower, eye rinse and fire extinguishers are located, and that you are capable of operating them. If an accident occurs there is no time to read the instructions.

Borrow equipment You shall always ask for permission before you borrow any equipment from any laboratory. If you have moved equipment (after permission), please leave a note with information on the new location of the equipment.

Eat or drink You are not allowed to eat or drink at the laboratories.

Label/content, date and owner All glassware and other utensils shall be marked with content, date and owner. It is also allowed to temporarily store harmless unmarked utensils in a suitable box on the desk, if the owner is identified on the box. Empty boxes can be found in the Process lab L213, or contact Bo Thunér. All potentially dangerous chemicals shall be labelled with appropriate warning labels. Labels are available where the chemicals are stored and in the Technical Service store M225. In addition, you must also label potentially cancerous reagents as carcinogens.

Keep clean Each laboratory bench and fume hood shall have a sign where it is posted who is responsible for that specific area. Labels, notes and signs shall always be understandable also for the English speaking staff and guests. Generally, you shall keep the desks and other laboratory areas as clean as possible. Never store your stuff on the lab benches. The lab space is limited.

11

HAZARDOUS WORK Risk analysis/risk assessment All new experiments/processes, including teaching activities, shall be subject for a risk analysis/risk assessment. Risk analysis is a dynamic process. You are encouraged to report to the responsible person if you identify potentially hazardous activities. Form and further information is available at: http://www.ifm.liu.se/admin/am/Riskbedomning-Riskassessment/

Material Safety Data Sheet Before handling any unknown chemical you must first read and understand the specific Material Safety Data Sheet (MSDS) that is delivered with the chemical and shall be made available in binders in the Chemistry lab L202, next to where the chemicals are stored. If you take the last of some chemical or utensil please be sure to always refill the supplies or inform Agneta Askendal.

Flammables Flammables shall of course never be exposed to open flames or electric engines etc where sparks could ignite the compounds. Bear in mind that some flammable organic solvents have the nasty habit of forming fumes that can “crawl” out of a ventilated hood. Furthermore, it is very important that you know how to handle spill of the specific flammable before you use it. Spill of some flammables may burst into flames spontaneously. More information on: http://www.ifm.liu.se/admin/am/Inflammable%20liquids.doc

Organic solvents Organic solvents shall be used under hood and are stored in a specific locker in Chemical store L210. Smaller amounts may also be temporary stored in ventilated cabinets.

Ethanol Access to ethanol is restricted. Contact Jeanette Nilsson if you need ethanol in your research.

Toxic and/or fretting compounds Toxic and/or fretting compounds shall always be handled in fume hoods. Toxic compounds shall be stored in a special locker in Chemical store L210. Acids and bases have two separate lockers in L210. When diluting strong acids, the acid must always be put into the water, not the vice versa.

Hydrofluoric acid, HF HF etching involves especially nasty hazards. At Applied Physics, working with HF is limited to one specific fume hood. You got to have an introduction before start working with HF. Contact Jeanette Nilsson for authorization.

12

Radioactivity We have permission to work with a very limited amount of radioactivity. Contact Pentti Tengvall before planning to use or ordering any radioactive material.

Genetically modified material All work with genetically modified material is restricted. Contact Carl-Fredrik Mandenius for more information.

Blood products Generally, the blood and other human body fluids (or products derived there from) that are being used at Applied Physics have passed the standard blood bank testing. Yet they shall always be treated as capable of transmitting infectious diseases. Always use gloves when handling blood, blood plasma or blood serum (except if you are performing experiments with samples of your own blood) and disposable lab ware. Blood to be wasted shall be sealed carefully and put in the containers for contaminated waste. Contact Agneta Askendal if you have questions about this.

Syringes and injection needles Syringes and injection needles shall be stored in locked compartments.

Pipettes You are not allowed to use your mouth as an aid when filling pipettes with liquids. Use pipette fillers instead.

Protective clothing/protection equipment Protective clothing and other relevant protection equipment shall always be worn when handling chemicals, refer to the safety document for each specific chemical. Use proper eye protection if there is a risk for splashes. Note that this also applies for your neighbours at the laboratory if there is a reasonable risk that they may become exposed to splashes from your work.

Gas tubes Gas tubes shall be chained to a support to avoid them from overturning. The protective cover must be applied before you move the tubes, even if it is just inside a laboratory. If the gas is toxic, the tube must be stored in a ventilated cupboard or hood. Applied Physics has a gas store in the basement. Contact Bo Thunér for purchase or returning tubes. More information: http://www.ifm.liu.se/admin/am/Gas%20cylinders.doc

Welding Welding is only allowed at certain locations where proper ventilation is available.

Laser The use of lasers is accompanied by strict regulations. Always contact Bo Thunér before using any laser equipment. 13

Glue If you use certain glues more than three times a year there is a recommendation that you shall first attend a special course. You must also go through a medical examination. Contact Helena Tegehed-Dahlin.

Electric mains powered equipment You are not allowed to perform any modifications, maintenance or any other kind of work inside equipment intended for connection to the electric mains. This applies to new designs of equipment as well as existing equipment. Contact Hans Sundgren if you find any need for maintenance or alterations on electric mains powered equipment.

Work with electricity A risk assessment must always be carried out before working with electric circuits. The risk assessment must be approved and signed by both the responsible senior and by Hans Sundgren. However, if it is clear that none of the following values can be exceeded: 50V, 10A or 200W a risk assessment is not needed for electric reasons exclusively.

Chemical waste Pack the chemical in an appropriate container and seal it properly. Mark the container with its content, date, your name and what lab it comes from. Place the container in the cupboards for waste in Chemistry lab L202. Waste labels can be found at the outside of the cupboards. Containers and waste labels can also be purchased in Technical Service store M225. Never (ever!) leave waste unattended, even if it is just water. Other users or cleaning personnel does not know that it is harmless. If you have any questions regarding the handling of waste, or suggestions for purchasing of specific waste labels, containers, etc., please turn to Jeanette Nilsson or Helena Tegehed-Dahlin. More information: http://www.ifm.liu.se/admin/am/Hazardous%20waste.doc

Sharp and/or contaminated waste Sharp objects (razor blades, syringes, injection needles, small glass waste, pieces of silicon wafers etc) and contaminated utensils (gloves, pipette tips, paper tissues, tops etc) shall be thrown in the metallic buckets. Put the lid on the buckets when they are filled to the maximum level (not to the edge, please) and fitted it with a waste label. Put the filled bucket in the Chemistry lab L202. Empty buckets can be found in Applied Physics store N203. If there is a frequently use of sharp utensils, please buy a special container made for that purpose. Never (ever!) put sharp and/or contaminated waste in the regular trash cans, regarding to the cleaning personnel!

Glassware Glassware for recycling shall be rinsed and put in the containers in L209. Please note that there are separate containers for transparent and coloured glass (or se Recyclable items below). This does not apply for broken glassware that shall be put in the metallic buckets.

14

OTHER RESTRICTIONS Recyclable items Put used corrugated cardboard in a container in the Goods room K112, and metal in a container in the basement (ask for location). Aluminium and glass (not broken glassware from lab) in containers in the corridor next to the Work Shop. Broken bulbs, used batteries and electronic trash (smaller) in the Technical Service supply in M225. Broken instruments/computers should be handed over to Peter Alm in M224. At the backyard of the Physics building there is a container, where you can put combustible waste.

Teaching activities and other guests at the laboratory Short-time guests shall work under careful supervision by a member of the research group. Supervisors and teachers are responsible for their students, master students and project workers. Perform a safety briefing before any laboratory assignment with students. Remember that teaching activities also require a risk analysis. This is the responsibility of the course leader.

Routines for purchasing Purchasing (over a certain sum) is regulated according to the rules for governmental activity in Sweden. Consult the regulations in the University handbook before placing an order: http://infoweb.unit.liu.se/inkop/upphandlingshandbok. Always consult your supervisor and administrator before placing an order. A copy of the purchase order shall be sent to your administrator and to Peter Alm, who is taking care of your parcel when it arrives. Purchases of chemicals shall always be done by Agneta Askendal.

Debit items and work for hire If you need the assistance of our engineers for work of longer duration, your research project will be accounted for a cost that is proportional to the working time. Support from our engineers of short duration is free of charge. In some occasions it is also necessary to charge for the use of specific equipment such as the evaporation equipments, the clean room in block B etc. Please note that your project must also pay for the use of several materials (wafers, metals, etc). Lists are provided near those specific items. Please note the consumption and what account to be charged. Companies are not allowed to use our laboratories without a prior agreement. Always consult Stefan Klintström for discussions regarding debit items and prior agreements.

15

LABORATORIES AT APPLIED PHYSICS CHEMISTRY LAB (Pentti Tengvall) Analytical scales Many people are using the analytical scales. Always clean spilled chemicals and always note the substance in the logbook when you are finished. This may be important information for the next user.

Wet silanization Inside the laboratory there is an area reserved for wet silanization. Please follow the posted protocols carefully during silanization and keep the door to this area closed. The glassware used during the silanization is forever contaminated and shall be treated as such. That is, it shall never leave the silanization room as other than waste. Always keep the door to the room closed. It is absolutely forbidden to put silanized lab ware in the dishwasher!

Radioactivity We have permission to work with a limited amount of radioactivity. However, you always have to clear with Pentti Tengvall before you handle any radioactive material in the laboratory.

Ellipsometric Before planning extensive experiments requiring ellipsometric analyses, please study the calendar next to the instruments to make sure the instruments are not reserved. Approved personnel may only reserve Ellipsometers. Contact Agneta Askendal.

Scriber The Scriber instrument (used for cutting silicon wafers) is a sensitive instrument that requires proper instructions before use. Please ask for help before attempting to use it, contact Bo Thunér or Agneta Askendal. Always note in the logbook, what you have cut.

Gloves At this laboratory we primarily use gloves to protect ourselves, not our samples. Please discard the gloves as soon as they are no longer needed to avoid spreading of contamination. Don’t throw used gloves in the wastepaperbin, instead use the metallic buckets.

PROCESS LAB (Bo Thunér, Jeanette Nilsson) Hydrofluoric acid, HF HF etching involves nasty hazards. Therefore we only handle HF in one specific area at Applied Physics. You must always have permission from your supervisor and proper training before performing any experiments involving HF. Contact Jeanette Nilsson.

16

7-up and TL2 Washing samples with 7-up and TL2 requires permission and proper training, contact Jeanette Nilsson.

Evaporation The evaporation equipments “Valfrid” and “Tekla” require proper training before use, contact Bo Thunér. The evaporation equipment “Alfred” is not for common use. If you need any work to be done in “Alfred”, contact Jeanette Nilsson.

Bonding/Welding The bond- and weld equipment are not for common use. Contact Evald Mild if you need help.

SURFACE CHEMISTRY LAB (Bo Liedberg) At this laboratory it is extremely important to avoid surface contamination. Therefore, all the glassware in this lab is only for use within the Surface Chemistry Lab. Tools and glassware cannot be borrowed for usage outside the laboratory. If you are uncertain about the cleanliness of glassware – don’t utilize it. Never bring glassware from other labs. It is absolutely forbidden to bring in things that have been in contact with silanez.

Gamma counter We have permission to work with a limited amount of radioactivity. However, you always have to clear with Pentti Tengvall before you handle any radioactive material in the laboratory.

DEVICE PHYSICS LAB (Wim Bouwens) Clean room course To gain access to the clean room one has to attend the “Clean room course”. It is an introduction to clean room environments, how it works and how to behave oneself in order to maintain a low dust level. Duration approximately one-hour theory and one-hour lab tour.

Lithography course In order to work with chemicals and/or do photolithography one has to attend the “Lithography course”. It is an introduction to photolithography and how to handle chemicals in the clean room. Duration, all day event; theory in the morning and practical work in the clean room in the afternoon.

Equipment course To be able to operate a specific type of equipment one has to attend an “Equipment course”. A set of three separate runs in order to learn to operate each specific instrument. First run: explanatory. Second run: guided operation. Third run: operation with minor help. Examples of equipment: PECVD/RIE, sputter, diffusion oxidation furnace etc. Contact Wim Bouwens for signing up for the courses. 17

SENSOR LAB (Mats Eriksson) At the Sensor lab, at S-SENCE, there are a number of gas-mixing systems. They are normally used to test gas sensors in controlled mixtures of different gases. Please, note that there are important instructions for the handling of the gas mixing systems in a binder at the entrance of the Sensor lab. Always contact Mats Eriksson before working at the lab.

ELECTRONIC LAB (Hans Sundgren) Bear in mind that there is a risk for exposed main power supplies at this laboratory.

WASHING UP (Bo Thunér, Jeanette Nilsson) TL1 and TL2 The hoods in this laboratory are intended for standard semiconductor cleaning procedures (TL1 and TL2) only. Please follow the posted instructions carefully and put the waste where intended. For handling TL2 one has to be introduced to the process to get an authorization. This is for minimize the damage, from the acid, on fume hood and ventilation. Contact Jeanette Nilsson.

Dishwasher There are too dishwashers; one for the IR group and one common, respect that. Please rinse the utensils to be washed-up carefully before placing them next to the “dirty” sign or in the dishwasher. It is absolutely forbidden to put silanized lab ware in the dishwasher!

WORKSHOP (Bo Thunér) Of course you have to know how to handle tools before start working here. Here you can find tools, drilling-machine, ultrasound washer, vacuum cleaner etc. There are also a bench where you can carry out smaller works.

TONGUE & NOSE LAB (Fredrik Winquist) Experimental set ups The X-Y table, electronic tongue systems (3) and electronic nose systems (3) are not for common use.

POLYMER LAB (Olle Inganäs) Photovoltaic experiments Use of the dedicated experimental set ups for photovoltaic experiments (determination of internal monochromatic quantum efficiency, solar simulator) for light emitting diodes (emission spectrometer, LED photometer) requires introduction by Fengling Zhang prior to use.

Evaporation The evaporation equipments “Polly” and “Malte” requires proper training before use, contact Bo Thúner. The use of vacuum evaporation requires permission from Fengling Zhang. 18

RUBBER LAB (Jens Andersson) The rubber lab is a part of the clean room in house B, separated from the device physics lab by a locked door. The lab is equipped with al necessary equipments for experiments with soft lithography in a controlled environment. To further minimize the risk of dust contamination, a laminar flow bench is installed for critical experiments. Connected to the main lab is a room for analyzing with a Zeiss fluorescence microscope and one potentiostate for electrochemistry experiments.

Introduction Every person that are going to work in the rubber lab, including the microscope room and PDMS, must first be introduced to the rubber lab routines by one already approved person of the Biorgel group. It will also be mandatory to sign an agreement that you have understood all the rules. Guests working together with one approved persons are excluded.

Prevent contamination These routines are set up to prevent dust contaminations in the lab. The intention is also to prevent contamination of other areas, as the device physics lab, from PDMS, silanes and other compounds used in the rubber lab.

Transport between laboratories To minimize the risk of contamination of the device physics lab no one is allowed to enter the lab from the service corridor. Neither are people in the device physics lab allowed to enter the rubber lab from the service corridor. However, if you need to bring samples between the labs put the sample in the service corridor. Leave the lab through the ordinary entrance and walk around. You must of course change clothes. Then you can pick up your samples from the service corridor.

PDMS When working with PDMS there are special dedicated area and routines to minimize the risk of contamination of the rest of the lab.

Cleaning All persons working in the rubber lab are dedicated to take part in the Friday cleaning of the lab between 09 and 10, every week on a rolling schedule basis.

Dressing The dress code in the rubber lab is slightly easier than in the device physics lab. But it is important to follow: clean room coat, gloves, shoes and hair cover. To get permission and training for working in the rubber lab, please contact Jens Andersson.
