Oxygen deficiency and V and Sb doping in TiO2 and SnO2: Influences on surface electronic structure

Abstract:

The influence of oxygen deficiency and of doping with V and Sb on the surface electronic structure of TiO2 and SnO2 will be reviewed. Despite the similarity in structure of the two materials, they differ significantly in their surface electronic properties. Oxygen deficiency in TiO2-x gives rise to a new electronic state in the top half of the bulk bandgap due to electrons self trapped on Ti(III) sites, whereas in SnO2-x new 5s-5p hybrid states appear toward the bottom of the bulk bandgap. V-...
