Lehrstuhl für Angewandte Physik


Description:


Research at the Chair for Applied Physics is devoted to electrons in solids since its foundations in 1948. We pursue fundamental research, which paves the way for innovative electronics beyond silicon electronics. Our focus is on material systems with unusual properties like graphene (a single layer of graphite) for ultrafast electronics, single organic molecules as smallest units for electronic functionality, but also semiconductors with wide bandgap (e.g. Silicon carbide) for powere electronics. Particular emphasis is put on the interaction of matter and light, in particular in Terahertz spectral regime.
