Abstract

Surface science studies of metal oxides have experienced a rapid growth.The reasons for this increasing interest are quite clear:after all, most metals are oxidized under ambient conditions, so in many instances it is the oxidized surface that deserves our attention.In addition, metal oxides exhibit an extremely wide variability in their physical and chemical properties, which are exploited in established and emerging technologies such as catalysis, gas sensing, and in energy conversion schemes.Scanning Tunneling Microscopy (STM) measurements, in combination with DFT calculations and area-averaging spectroscopic techniques, have been instrumental in understanding the atomic-scale properties of the surfaces of a number of oxides.In the talk I will give recent examples drawn from studies of bulk single crystals, such as TiO2, Fe3O4, In2O3, and SrTiO3.
