Abstract

Sb-doped BaSnO₃ is synthesized by the conventional solid-state reaction method changing a concentration of Sb. Electric resistivity of synthesized specimens decreases with increment of doped Sb concentration. In order to investigate an influence of Sb-doping on the electronic structure of BaSnO₃, its valence band electronic structure is examined by the photoemission yield spectroscopy (PYS), which shows additional occupied band above the top of the valence band of BaSnO₃ due to the Sb-doping. First-principles calculations are also carried out to obtain change in electronic structures of BaSnO₃ by Sb-doping, which supports the PYS results.
