Great News for our group: We will relocate to Frankfurt soonWe have been successful in aquiring funding from the DFG. Sven has been accepted for funding in the frame of the "Heisenberg Programme". In addition, Felix Jungwirth will continue working in the group and start as a PhD student. We are looking forward to close collaboration with M. Huth from the physics department. It is a pleasure to work in this highly interdisciplinary field of materials chemistry/science. |

MRS Fall Meeting in BostonSven and Michael presented our work on metastable Ge-based materials in two talks during the week. We had a very good time of scientific exchange with colleagues in the field. Moreover, former MSc student Lukas Hrachowina gave an interesting talk related to his work on single nanowire PV conducted in Lund. The MRS meeting was a great platform to chat with active and new collaborators and also good friends from different parts of the world.
