His research is focused on thin films, surfaces, functional materials, nanomaterials, nanoalloys, nanocomposites, nanostructuring and related applications. For that, a large variety of preparation methods (PVD, CVD, ALD, Laser, Ion Beams, etc.) and a bunch of analysis methods (XRD, SEM, FIB, EBSD, EDX, TEM, EELS, Nanoindenter, UV-vis, Raman, electrical characterizations, etc.) is used. Applications range from electronics, plasmonics, photocatalysis, mechanical applications, hard surfaces, dewetting, nano-metallurgy, and further topics.
