Abstract

We have measured experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) and the resonant enhancement of valence photoemission at the Ti 2p threshold for Ti₂O₃. A satellite structure of the 2p XPS is interpreted as the charge transfer (CT) satellite based on the analysis with a cluster model. The behavior of the resonant photoemission is understood in terms of the effect of strong covalency hybridization. It is shown that Ti₂O₃ is classified as an intermediate-type insulator between the CT insulator and the Mott-Hubbard insulator.
