In the Department of Low-dimensional Systems focus is also kept on sensorics. Graphene, carbon nanotubes and other nanocarbon material evince promising electronic and chemical properties which could be efficiently used in sensorics. Detection of ppm concentration of target gas species was sufficiently realized using carbon nanostructures. Graphene functionalized with polymers showed promising gas adsorption/desorption behavior as well. In the presence research is mostly focused on fundemental study of gas adsorption to graphene and its impact to graphene’s electronic band structure. For that purpose graphene field-effect-transistors are fabricated and their transport characteristics are measured in-situ during gas adsorption/desorption. These effects could be also studied at different temperatures. The lab is also equiped with microfluidics devices for liquid sensing.
