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

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...
