Spectro-Microscopy

Spectro-Microscopy

Our investigations focus on the preparation and modification of thin oxide films on metal supports and metal nanoparticles on oxides and on the structural, electronic and chemical properties of these systems for thermal catalysis.

The experiments are performed with the high resolution spectro-microscope SMART (Spectro-Microscope with Aberration Correction for many relevant Techniques) operating at the BESSY II electron storage ring. This aberration corrected and energy filtered Low Energy Electron Microscope (LEEM) / Photo-Emission Electron Microscope (PEEM) combines microscopy, spectroscopy and diffraction of photo-emitted and reflected electrons. It allows for real-time observations of surface processes like oxidation, structure formation or chemical reactions.
