Surface science, in particular evaluation of the mechanisms of optical excitations in nanoparticles and the related physical and chemical processes at their interfaces.
Physics and chemistry of water and carbon materials are of special interest.
UHV-based spectroscopies (HREELS, Mass, AES, XPS, Raman …), physical/chemical transformations/reactions (thermal, photo-, e-induced), intercalation, optics, nanofabrication.
Focus of present and future research:
- Optimization of the charge transfer in photoactive nanocomposites for efficient photocatalysis and PV devices.
- Water (ice) interaction with surfaces and water photo dissociation.
- Instrument development.
