We have studied the electronic structure of BaPb 1-x Bi x O 3 and its changes across the composition-dependent metal-semiconductor transition using photoemission and O 1s x-ray-absorption spectroscopy. For the parent insulator BaBiO 3 , the peak-to-p

In order to reveal the microscopic origin of the metal-nonmetal transition in NiS, we have studied the Ni 2p x-ray-absorption spectra of substituted systems Ni 1-x M x S (M=Fe,Co), whose transition temperature T t varies from ∼500 K (Ni 0.5 Fe 0.5

We present the O 1 s x-ray absorption spectra of two series of transition-metal oxides including all the d 0 oxides of the groups IVa and Va elements, namely TiO 2 −ZrO 2 −HfO 2 and V 2 O 5 −Nb 2 O 5 −Ta 2 O 5 . The spectra correspond to tran

The electronic structure of mesoscopic NiO particles was studied by means of soft X-ray absorption spectroscopy. The Ni 2p spectra show convincingly that the changes in the electronic structure of mesoscopic NiO do not involve Ni 3+ as previously tho

The electronic structure of Mott-Hubbard-type Ti and V oxides have been studied by photoemission and X-ray absorption spectroscopy. The evolution of the spectra across the Mott transition indicates characteristic transfer of spectral weight from the

We present the V2p and O1s X-ray absorption spectra of V 2 O 3 , VO 2 and V 2 O 5 . The V2p spectra show strong multiplet effects caused by large 2p-3d and 3d-3d Coulomb and exchange interactions. The spectra exhibit noticeable chemical shifts and co

The N1s XAS spectrum of a reference TiN sample is compared to an N p-projected DOS. Good overall agreement is found except for a small discrepancy at the edge which could be due to core-hole effects. Teh N1s XAS spectra of N 2 chemisorbed on Ti (3000

The oxidation of TiN in an oxygen flow at temperatures in the range 300–500 °C has been studied by means of soft x‐ray absorption spectroscopy. The analysis of the experimental results indicates that O progressively displaces N to form TiO2. The
