We welcome all users to access the equipment for fundamental research and development in the fields of soft electronics and functional materials. Many Täppan Cleanroom users come from academic research environment, mainly LiU. The lab is also open for the entire academic and industrial materials research community. For inquiries regarding access and accreditation, please, contact Slawomir Braun, slawomir.braun@liu.se  

Coating and Microfabrication 

High vacuum thermal evaporators are available for the deposition of common metals (Al, Ag, Au, Cr). Metal patterns with resolution down to ~50 碌m are achieved with plastic shadow masks made via laser patterning or using a flat-bed cutter. Standard photolithography facilities are available to achieve smaller features of ~1 碌m using etching or lift-off techniques.  

Soft patterning 

Plasma enhanced CVD is available to coat insulating layers and the three 鈥淩eactive Ion Etching鈥� setups are used to pattern polymeric materials.  

Synthesis and coatings 

Chemical synthesis and ink formulations are carried out inside state-of-the-art fume hoods and nitrogen gloveboxes. Homogenizers, ultrasonic bath sonicators, and high-power probe sonicators are available to attain homogeneous dispersions. The resulting mixtures are deposited in a variety of manners i.e. atomically thin coatings are achieved with two 鈥淟angmuir-Blodgett鈥� coaters, programmable spin coaters are used for tens-hundreds of nm coatings, blade coating for 碌m thick coatings, while electrospinning and freeze-dryers are available to attain free-standing bulks.  

Material characterization 

Surface morphology studies are carried out with optical microscopes, optical & surface profilometers, atomic forces microscopes (AFM), and a scanning electron microscope (SEM). Energy-dispersive X-ray spectroscopy (EDX) capability is available within our SEM system, providing the possibility to assess chemical composition of samples. UV-Vis-NIR, FTIR and ATR are available for absorption studies while dielectric properties are studied with a dielectric spectrometer for films and liquids. 
Climate and Humidity chambers are used for studying materials at temperatures above 0 鈦癈 and from dry to wet conditions. Low-temperature vacuum measurements are carried out inside four and six arm cryogenic probe stations with temperature ranges of 10-500K. Complete Thermoelectric (TE) characterization facilities have been developed in-house for thin films and bulk (solid and liquid) materials.  

Device characterization 

Two state-of-the-art Keithley 4200 systems with probe stations are used for diodes, transistors, and complementary circuit analysis. Electrochemical characterization of materials and devices (supercapacitors and batteries) are performed by potentiostats from Gamry and Bio-Logic. 

Here you may find a wide range of equipment allowing possibility to develop, pattern, and characterize advanced soft functional materials and electronic devices of the future.

Enquiries about lab use: slawomir.braun@liu.se

Täppan Cleanroom is a complex environment, so good laboratory practice is essential if laboratories are to be safe places in which to work.  

Our open research facility is available to academic research groups, start-ups, and company users. All new users are required to complete mandatory training. It is a pre-requisite for all those who wish to access Täppan Cleanroom as a user. This covers such areas as safety, handling chemicals, proper cleanroom behaviour, and specific information concerning the Täppan Cleanroom.
