My research interest is centered around novel organic semiconductors, based on organic molecules as well as hybrid perovskites. These materials hold great potential for the use in next generation energy related applications such as light-emitting diodes and photovoltaics, as well as electronic applications like transistors and memory devices.
In these multilayered structures, charge transport barriers between the different semiconductors or to the inorganic contact materials play a crucial role for the device performance. Therefore, my research is focus on measuring and understanding the energetic properties of individual materials as well as their alignment at interfaces using photoelectron spectroscopy. I want to correlate findings regarding the energetic properties with the electronic performance and device characteristics. Furthermore, I investigate the concept of controlled molecular doping, which makes it possible to improve device performance due to the passivation of unwanted trap states and to control conductivity as well as the Fermi level positions.
