Valence-band electronic structure ofMoS2and Cs/MoS2(0002) studied by angle-resolved x-ray photoemission spectroscopy

The local atomic and electronic structure of La 0.5 Sr 0.5 MnO 3 was investigated at different annealing temperatures (TA) by X-ray absorption spectroscopy (XAS) and photoemission spectroscopy (XPS). The extended X-ray absorption fine structure indicates that the MnO 6 octahedral distortion is reduced by increasing TA. The chemical shift for the sample with TA = 1350° C measured by XPS of Mn 2p core level demonstrates the increasing of Mn 3+ ions content. From the deconvolution of valence band photoemission spectra, the number of eg electron is also proved to increase with increasing TA. It is also demonstrated that there is a strongest hybridization between O 2p and surrounding atomic orbital states in sample with TA = 1350° C , which is consistent with valence band photoemission.

ABSTRACTWe report here the results obtained for the valence band of four compounds from the Al-Cr-Fe system, all being approximants of the decagonal quasicrystalline phase as probed by a combination of X-ray emission and X-ray photoemission spectroscopy techniques. Salient features are d-d and p-d hybridizations at the Fermi level and in its close vicinity as well as a repulsive interaction between the d states of the two transition elements. Within about 4 eV below the Fermi level Al states are suggested to be of more localized-like character in the Al-Cr-Fe samples than in Al-Cu-Fe ones.
