Oxide Surfaces at the Atomic Scale: Defects, Adsorption, Reactivity

DieboldCopyright: Prof. Dr. Diebold

Fundamental investigations into the surface properties of metal oxides have experienced a continued 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 points of view. 

By using Scanning Probe Microscopy measurements, in combination with Density Functional Theory calculations and area-averaging spectroscopic techniques, great strides have been made in understanding the atomic-scale properties of the surfaces of several oxide materials.  In the talk I will give examples drawn from our recent studies on TiO2, Fe3O4, In2O3, ZrO2, and perovskites.
