Abstract:
Rutile-type transition-metal oxides are extremely fertile areas of study both for
fundamental and technological reasons due to the range of physical properties they
present, such as insulating TiO2, semiconducting Sn02 and metallic RuO2. The
chemical bonding of such rutile-type oxides is assumed to have an essentially ionic
character despite differences in the outer electronic structures of the cations, from
empty outer shell (Ti 4+), to partially filled (Ru 4+) to filled (Sn 4+), but has been
shown to become progressively more covalent, and details of their electronic structure are still under intense experimental study and theoretical consideration. To this end, resonant x-ray absorption and emission spectroscopy (RXES) provides a sensitive element-specific and symmetry-selective probe of the unoccupied and occupied electronic bandstructure of these materials.
