Resonant inelastic soft x-ray scattering of CdS: a two-dimensional electronic structure map approach
Resonant inelastic x-ray scattering (RIXS) with soft x-rays is uniquely suited to study the elec-tronic structure of a variety of materials, but is currently limited by low (fluorescence yield) count rates. This limitation is overcome with a new high-transmission spectrometer that allows to measure soft x-ray RIXS "maps." The S L2,3 RIXS map of CdS is discussed and compared with density functional calculations. The map allows the extraction of decay channel-specific "absorp-tion spectra," giving detailed insight into the wave functions of occupied and unoccupied elec-tronic states.
