• 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
