Surface & Interface Science Marburg

We do basic experimental research in the field of surface and interface science. Our investigations focus on optical excitations, electron transfer processes and vibrational properties of solid surfaces and internal interfaces. Our main methods are ultrafast laser spectroscopy, time-resolved photoemission, scanning tunnelling microscopy and infrared spectroscopy. Our experiments on well-defined monocrystalline metal and semiconductor samples are usually carried out in ultra-high vacuum. In recent years, the focus has shifted from very simple model systems such as hydrogen on silicon or image-potential states to more complex organic/inorganic interfaces and to surfaces and interfaces of novel materials such as topological insulators or two-dimensional semiconductors.
