Study of the energy transport and dissipation processes on the nanoscale in metals, dieeletrics and heterosystems after strong localized electronic excitations to gain a better understanding of ion-surface interactions using ion beams created at accelerator facilities (GANIL, GSI) and in an EBIT. The results will help to establish methods for the controlled modification of surfaces or nanostructures and their properties by swift heavy and highly charged ion irradiation. The work of this group is supported by the DFG and the BMBF.
Awards include among others the Dorothea-Erxleben-Stipendium of the state of Niedersachsen, the Heisenbergstipendium of the DFG, and the Universitätspreis of the Universität Osnabrück for the best habilitation thesis.
