Our Research Interest

Organic Electronics

Our research in the field of Organic Electronics is concentrated on electronic excitations in molecular single crystals, crystalline thin films as well as single molecules and their interplay with the structural and electronic characteristics on nanometer length scale. Disclosing the fundamental processes together with their dependence on morphology and temperature allows for a fundamental understanding and, thus, improvement of the device performance of organic field-effect transistors (OFETs), organic photovoltaics (OPVs) as well as OLEDs.

Organic Thermoelectrics

Upon primary energy consumption a significant amount of waste heat at moderate temperatures of around 100°C is generated. Regarding recent efforts on sustainable, environmental-friendly energy sources it is thus of utmost importance to take advantage of these losses by means of thermoelectric generators (TEGs) which directly recover waste heat into electric power. In contrast to well-established inorganic TEGs, mainly based on doped Bi2Te3, organic van-der-Waals bound semiconductors constitute a promising alternative material class for next-generation, low-cost and green-technology TEGs.

Metal-Organic Hybrid Structures

Metal-organic hybrid structures offer unique possibilities for application in already existing devices, such as photo-detectors or organic light-emitting diodes (OLEDs), as well as in novel photonic architectures. Furthermore, the coupling between the electronic excitations of a molecular thin film and the local plasmonic resonances of a metallic nanopattern in close proximity can tune the optical properties of the organic layer or even generate new plasmon-polaritonic states, also called plexcitons.
