Charge transport and light-matter interface in the solid state
Research at the Chair of Applied Physics has been concerned with electrons in the solid state since its foundation in 1948. We conduct fundamental research to understand elementary physical processes and new materials. Our research focuses on semiconductor materials such as silicon carbide, which we study with respect to power electronics, and graphene, which grows epitaxially on its surface and has outstanding quantum mechanical properties as atomically thin carbon. Furthermore, we investigate molecular materials, for example the electrical properties of single molecules.
Since 2015, our research strategy has shifted towards the light/matter interface. Here we are interested, for example, in how light fields can be used to drive currents and how currents generate light. We are interested in new functionalities in the terahertz frequency range and the properties of point defects in the solid state, which we are investigating with respect to quantum information technologies.
