"Frontiers of Surface Sensitive Electron Microscopy"

Microscopy with Low Energy Electrons (LEEM) and Photoemission Electron Microscopy (PEEM) has graduated over the last decade from being a fascinating novelty to being an extremely valuable tool in the understanding of fundamental processes at surfaces. The microscopes usually provide in-situ capabilities and enable scientists to study film growth, phase transitions, and the formation of structures in real-time. The use of synchrotron radiation extends the technique into chemical imaging, spatially resolved photoemission spectroscopy, and magnetic imaging. At the same time, with computers becoming more and more powerful, many of the experimentally observed phenomena can be theoretically understood and simulated. While the techniques are by now well established, new experimental challenges are sought; the resolution is improved by using aberration correctors, and the time resolution of the photoemission microscopes is extended into the femtosecond timescale. Using pulsed synchrotron radiation, the ultrafast magnetic response of spin structures during switching processes can be made visible. By using femtosecond laser pulses, images of surface plasmon polariton waves can be obtained while the waves travel along a nanostructure. Along these lines, the optical near fields near metallic structures can be observed and even manipulated. The aim of the symposium is to present state-of-the-art applications of LEEM and PEEM along with theoretical explanations of the observed phenomena.
