Zusammenfassung:
The contributions of Sn 5s and Ti 4s states to the valence band
electronic structure of Sn-doped anatase have been identified by hard
X-ray photoelectron spectroscopy. The metal s state intensity is
strongly enhanced relative to that of O 2p states at high photon
energies due to matrix element effects when electrons are detected
parallel to the direction of the polarisation vector of the synchrotron
beam, but becomes negligible in the perpendicular direction. The
experimental spectra in both polarisations are in good agreement with
cross section and asymmetry parameter weighted partial densities of
states derived from density functional theory calculations. (C) 2016
