We have measured bulk sensitive photoemission spectra of pure vanadium sesquioxide (V2O3) in its metallic phase as a function of different surface preparations. We observe the presence of a clear coherent peak in the vicinity of the Fermi level and of satellites intensities at the V 2p core level. After scraping, the coherent intensities are almost completely suppressed in both core level and valence band. Our results suggest a remarkable change of the screening properties in strongly correlated systems when going from the surface to the volume.

Abstract

We have measured bulk sensitive photoemission spectra of pure vanadium sesquioxide (V2O3) in its metallic phase as a function of different surface preparations. We observe the presence of a clear coherent peak in the vicinity of the Fermi level and of satellites intensities at the V 2p core level. After scraping, the coherent intensities are almost completely suppressed in both core level and valence band. Our results suggest a remarkable change of the screening properties in strongly correlated systems when going from the surface to the volume.
