Abstract

We have systematically analyzed 2p, 3p and 3s core-level x-ray photoemission spectra (XPS) for a series of transition metal (TM) sesquioxides M₂O₃(M=Ti, V, Cr, Mn, Fe) by means of an MO₆ cluster model. The character of the insulating energy gap is also studied on the basis of the XPS analysis. It is shown that M₂O₃ from Ti₂O₃ to Mn₂O₃ are classified as the intermediate-type insulator between the charge transfer(CT) insulator and the Mott-Hubbard(MH) insulator and Fe₂O₃ is classified as the CT insulator.
