Spectroscopic Tool

An end-station for X-ray Raman scattering spectroscopy at beamline ID20 of the European Synchrotron Radiation Facility is described. This end-station is dedicated to the study of shallow core electronic excitations using non-resonant inelastic X-ray scattering. The spectrometer has 72 spherically bent analyzer crystals arranged in six modular groups of 12 analyzer crystals each for a combined maximum flexibility and large solid angle of detection. Each of the six analyzer modules houses one pixelated area detector allowing for X-ray Raman scattering based imaging and efficient separation of the desired signal from the sample and spurious scattering from the often used complicated sample environments. This new end-station provides an unprecedented instrument for X-ray Raman scattering, which is a spectroscopic tool of great interest for the study of low-energy X-ray absorption spectra in materials under in situ conditions, such as in operando batteries and fuel cells, in situ catalytic reactions, and extreme pressure and temperature conditions.

AbstractWe report the MBE growth of various (SimGen)p atomic layer superlattices (ALS) and their characterization by Raman scattering spectroscopy, x-ray diffraction and photoluminescence. The structural properties of ALS prepared on (100) Si, (100) Ge and on various Si1-xGex (0.5<×<1) buffers were compared. Phonon peaks due to folding of acoustic modes were seen by Raman scattering spectroscopy in the frequency range 15-250 cm-1. The observed Raman spectra from the ALS were interpreted on the basis of a theoretical analysis of these systems. The study provided an estimation of the interfacial sharpness of the ALS. The photoluminescence investigation on annealed specimens revealed features between 800 and 900 meV that were ascribed to known dislocation lines in Si. No strong luminescent signal that could be unambiguously related to a direct bandgap behavior was detected.
