Surfaces are the outer boundary of any condensed material. They dominate the interaction with the environment and play a decisive role in numerous natural and technological processes, ranging from heterogeneous catalysis, sensor technology and nanotechnology to advanced functional materials. A major interest of the group is exploring molecular interactions at surfaces and interfaces associated with the formation, function and degradation of materials structures, devices, delivery vehicles and nanomedicine. We target a thorough understanding of various physical and chemical processes on an atomic level by means of modern electron and X-ray analytical methods.
