The subject of surface and interface analysis is dedicated to phenomena and their causes for corrosion and friction as well as to the functionality and mode of action of interfaces. This concerns interfaces between solids and gases, solids and liquids as well as between solids themselves. The materials range from mechanical engineering materials (metal and ceramics), lightweight materials (stability, aging and functional principles of heterogeneous polymer materials) to typical optical and electronic materials.

This includes a variety of methods for determining the chemical composition and physical mode of action of internal and external interfaces with the highest sensitivity or, in the case of imaging, also with the highest possible local resolution. Examples include X-ray photoelectron spectroscopy, various electron microscopy methods, secondary ion mass spectroscopy and spectro-electrochemical methods.

Tribological methods in media of alternative energy sources, micro- and nanostructuring as well as infrared spectroscopy with nanometer resolution, also with simultaneous determination of mechanical and electrical parameters, are also offered. Small angle X-ray scattering for the characterization of nanoparticles and their interfaces to fluids is also used.

Questions of safety and thus the functionality of surfaces and interfaces in materials engineering and chemistry are the core area of our work. We disseminate our scientific findings through a large number of publications, increasingly with free access. The technological developments flow into patents or are developed within the framework of cooperation with industry.
