With respect to nanotechnology our focus lies in the production of nanometer-sized defects on various kinds of surfaces. For the formation of such defects, highly-charged ions have been shown to be a suitable tool. Read more ...

The studies of friction on a nanometer-lengthscale, nanotribology, is another topic in nanotechnology, to which our group contributes in collaboration with the Austrian Excellence Center for Tribology AC2T.

These investigations are carried out using state-of-the-art atomic force microscopes (e.g. a Cypher AFM from Asylum Research).
