Description
Surface electronic states associated with defects produced by Ar-ion bombardment of TiO2 crystals have been studied by ultraviolet-photoemission, electron-energy-loss, and Auger spectroscopy and low-energy-electron diffraction. Evidence is given for three distinct phases dependent upon the extrinsic surface-defect concentration. Phase I contains isolated surface states 0.7 eV below the conduction band, phase II is associated with the creation of Ti3+ pairs, and phase III consists of a surface layer or ordered Ti2O3
