摘要：

An in-gap state formed in the band gap of TiO2 upon surface oxygen-vacancy doping has been studied by angle-resolved photoemission spectroscopy. The in-gap state with a formal d(1) configuration exhibits a small (1X1) k dispersion, though it never crosses the Fermi level for all the: oxygen-vacancy concentration range. We propose that a polaron interaction is responsible for the localization of doped electrons in the in-gap state.
