In the last decades “Organic Electronics” is a rapidly emerging field of physics, chemistry and related science and organic electronic devices like light emitting diodes, field effect transistors or solar cells are entering the market. However, the mobilities of slightly disordered organic thin films are often rather poor and limit device performance. Moreover, the energy-level alignment at organic/organic and organic/inorganic interfaces, which are inherent to organic devices, is not understood in a sufficient way. Ultraviolet photoelectron spectroscopy (UPS) is an effective tool to get deep insight in the electronic structure at relevant interfaces. Moreover, complementary surface science techniques like the X-ray standing wave technique or X-ray photoelectron spectroscopy can give a comprehensive insight in organic/metal interfaces.

His research is focused on functional hybrid organic/inorganic and organic/organic interfaces with angle-resolved ultraviolet photoelectron spectroscopy (ARUPS) as main experimental tool. The research resulted so far in more than 40 publications in SCI indexed journals like Nature Materials, Nature Chemistry, Physical Review Letters, Advanced Materials or Journal of the American Chemical Society. These publications are cited over 1200 times, resulting in an h-index of 18.
