STM of Defects, Adsorbates, and Nanostructures at Oxide Surfaces — •Ulrike Diebold — Institute of Applied Physics, TU Vienna, Austria

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, bulk metal oxides exhibit an extremely wide variability in their physical and chemical properties. These are exploited in established and emerging technologies such as catalysis, gas sensing, and energy conversion schemes, where surfaces and interfaces play a central role in device functioning. Hence a more complete understanding of metal oxide surfaces is desirable from both a fundamental and applied point of view. By using STM measurements, in combination with DFT calculations and area-averaging spectroscopic techniques, great strides have been made in understanding the atomic-scale properties of the surfaces of several oxides. In the talk I will give recent examples drawn from studies of bulk single crystals including TiO2, Fe3O4, In2O3, and SrTiO3.
