Biography
My research is focussed on synthesis and characterization of thin film materials for various applications. I work primarily with carbon-based materials such as carbides and graphene, but also with borides and oxides. An important part of the research is the design of multi-functional materials with a specific microstructure. Examples are, nanocomposites, amorphous films, and multilayer structures with an unique combination of mechanical, tribological and electrical properties.
