High Kinetic Energy Photoelectron Spectroscopy at BESSY — •Mihaela Gorgoi¹, Svante Svensson², Marcel Mertin¹, Franz Schäfers¹, and Walter Braun¹ — ¹BESSY GmbH, Berlin, Germany — ²Uppsala University, Uppsala, Sweden

The present work will show the investigation possibilities offered by the recently developed high kinetic energy photoelectron spectroscopy (HIKE) at the Berliner synchrotron light source. Hard x-ray photoemission has proven to be a non-destructive depth profiling tool for the characterisation of bulk electronic properties of different types of materials as well as interface properties of organic and inorganic thin films and multilayers. The HIKE end station operates at the KMC-1 bending magnet beamline. Electron spectra have been recorded using x-ray energies from 2 keV up to 12 keV excitation energies. Exemplifying results will be given in order to demonstrate the performance of the technique and its advantages.
