Organic Semiconductors: Fundamental Research and Devices

Organic semiconductors, in particular polyaromatic hydrocarbons, have experienced a tremendous increase in attention mainly due to their utilization in up-to-date opto-electronic thin film devices, such as organic light emitting diodes (OLEDs). Further promising results on organic thin film transistors (OTFTs) and photovoltaic cells (OPVCs) have been achieved, paving their way towards innovative device concepts for future application. Yet, many fundamental processes in this material class are still unsolved or even have to be discovered.
Therefore, the research activities of our group aim for a fundamental understanding of the material inherent properties, like charge carrier mobility or exciton diffusion length, in crystalline organic materials and for an implementation of the gained knowledge to further improve existing thin film devices concepts, namely OTFTs and OPVs, as well as to develop strategies for novel molecular electronics, such as single photon sources on demand.
