Research activity of our group focusses on investigations of the optical properties of semiconducting single crystals as well as epitactically grown structures with wide bandgaps such as CdS, ZnSe and GaN. Continous wave (cw) and time-resolved optical spectroscopy is performed in regimes of extreme external parameters such as high magnetic fields, very low temperatures (mK) and time resolved down to the fsec-range.
