| Complex oxide surfaces studied at the atomic scale by non-contact AFM/STM and DFT |
| Speaker: | Igor Sokolovic (TU Wien, Institut für Angewandte Physik (IAP)) |
| Abstract: | The majority of solid state matter naturally appears in the form of an oxide, which are highly stable in atmospheric conditions, and therefore constitute a vast research area on a broad range of their properties. I will present results obtained on two representative materials: The model binary oxide rutile TiO2(110) and the prototypical perovskite oxide SrTiO3(001) oxide. Both were studied at the atomic scale at low temperatures in ultrahigh vacuum using combined non-contact atomic force microscopy (nc-AFM) / scanning tunneling microscopy (STM) experimental setup, and the results were directly compared to density functional theory (DFT) theoretical modeling.
Rutile TiO2(110) interacts with the small O2 [1] and CO [2] gas molecules by altering its polaronic ground state. A bulk-terminated SrTiO3(001) surface can be obtained only through ferroelectricity-assisted cleaving in ultrahigh va |
