Study ofV2O3by X-Ray Photoelectron Spectroscopy

The band structure of ${\mathrm{V}}_2$ ${\mathrm{O}}_3$ below the Fermi level has been studied by x-ray photoelectron spectroscopy both above and below the Néel temperature. Aside from normal bands associated with atomic states from 20 to 640 eV, a valence band with structure was observed in the range 0-10 eV. The results are compared to soft-x-ray-emission and -absorption results and to theoretical predictions concerning the band structure of ${\mathrm{V}}_2$ ${\mathrm{O}}_3$.
