Organic Electronics

Main content

This page gives an overview of our research in the field of organic electronics. For further information please see also our publications.

Organic electronics is of currently of high interest and covers organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVs) and organic thin-film transistors (OFETs). Our research focuses on the physics of organic semiconducting crystals and on thin film devices. We produce polycrystalline and amorphous thin films by evaporation or spin coating. Moreover, we grow high purity crystals using physical vapor transport. We investigate the physical properties of these materials using devices such as capacitors, transistors and inverters. In addition to organic semiconductors, we also analyze insulators and contact materials.

We carry out experiments in ambient atmosphere, but also under controlled conditions, that is, in high vacuum, under different gas atmospheres and in distinct temperature regimes. This allows us to study the device performance as well as fundamental material properties such as the density of states distribution.

Based on an in-house developed numerical model we can simulate transistors with various density of states distributions giving the opportunity to compare experimental results with simulations.
