We develop materials and coating processes for the functionalisation of surfaces of molds, forming tools, medical and micromechanical as well as optical components and adapt the processes to industrial standards. One outstanding research topic is the investigation of self-organizing, structure-forming phenomena during layer growth and the exploitation of these phenomena to control surface properties such as reflection, wetting, adhesion and haptics. A unique feature of this department is the extensive knowledge about the relationship between coating deposition parameters and the resulting microstructure and internal stresses of the coating. Another area of work is the development of layered materials or even nanolaminates with strong barrier properties with the aid of simulations for high temperature applications.

Functional nanostructures for optics and microsystems
Component function can be controlled to a great extent through surface structuring. Optical, medical and tooling technology applications each require different surface textures on a micro and nano scale. These are generated by exploiting the self-organization effects during the growth of PVD layers. For instance: surfaces can be made water and dirt proof, the cell adhesion on the surface of an implant can be controlled, and polymer components ...
