Ultrafast Photoemission Microscopy — •Frank-J. Meyer zu Heringdorf, Dagmar Thien, Liviu I. Chelaru, Oliver Heinz, Ping Zhuo, Dietrich von der Linde, and Michael Horn-von Hoegen — Institut für Experimentelle Physik, Universität Duisburg-Essen (Campus Essen), 45117 Essen, Germany

The combination of ultrafast spectroscopy with photoemission microscopy is a rather challenging venture, that has so far only been attempted at few places around the world. Here we describe a novel experimental setup at the University of Duisburg-Essen that combines photoemission electron microscopy (PEEM) with pulsed fs-laser sources to study the energy dissipation of excited electrons in self organized nanostructures. The presentation describes the recent status of the setup and first experimental results of self-organized Ag nanostructures on Si(001).
