Surface & Interface Science Marburg

The group conducted basic experimental research in the field of surface and interface science at the Department of Physics of the University of Marburg from 1999 to 2025. The investigations focussed on optical excitations, electron transfer processes and vibrational properties of well-defined solid surfaces and internal interfaces. The main methods were ultrafast laser spectroscopy, time-resolved photoemission, scanning tunnelling microscopy and infrared spectroscopy. The most recent experimental developments of the group were time-resolved photoemission orbital tomography in collaboration with Peter Puschnig (Graz) and Stefan Tautz (Jülich) and subcycle momentum microscopy in collaboration with Rupert Huber (Regensburg). Research activities using these methods are presently continued at the Regensburg Centre for Ultrafast Nanoscopy (RUN) of the University of Regensburg.
