Motivation and Research Strategy

Interface-dominated functional materials are nowadays used in many applications, e.g. in nanotechnology, catalysis, chemical sensing, gas separation, and storage as well as in molecular electronics. For materials improvement by rational design the knowledge of structure-function-relationships are essential. Thus we synthesize functional materials and extensively characterize them with modern methods of surface and bulk analysis.

Especially, the interactions with nearby molecules are in our centre of interest. Afterwards we investigate the properties and function of the materials during their operation (“in –situ”). The correlation of all results gives us insight in the structure-function-relationships of the material and therefore strategies to develop materials with better performances.
