Adsorption on Oxide Surfaces
- Gold on V2O3
- Mg phthalo-cyanine on V2O3
- Determination of absorption sites for molecular (CO, H2O, MgPc) and atomic species (Au, Pd, Fe, Ag)
- Exploring the role of lattice defects and charge-transfer processes in the adsorption behavior
- Identifying adiabatic and diabatic diffusion prior to adsorption
Gold atoms on V2O3
- Oxide defects irrelevant for Au-adsorption
- Spatial distribution of Au given by band-bending effects due to bulk defects
Topography and state-density maps for empty (middle) and filled states (right) of V2O3 films with atomic Au species (15×15nm2)

Mg phthalocyanine on V2O3
- MgPc preferentially binds to defects
- Asymmetric appearance of MgPc marks local defect interaction
