Electronic Structure Study of Copper-containing Perovskites

The electronic structure of iridium and its oxides

Iridium-basedmaterials are among themost active and stable electrocatalysts for the oxygen evolution reaction. Amorphous iridium oxide structures are found to bemore active than their crystalline counterparts. Herein, we combine synchrotron-based X-ray photoemission and absorption spectroscopies with theoretical calculations to investigate the electronic structure of Ir metal, rutile-type IrO2,...

Electronic structure of spinel oxides: zinc aluminate and zinc gallate

The electronic structure of zinc aluminate (ZnAl2O4) and that of zinc gallate (ZnGa2O4) were studied by the self-consistent tight-binding linearized muffin-tin orbital method with the atomic sphere approximation. The calculated results predict these zinc-based spinel oxides to be direct-gap materials. The direct gap at 0 is found to be 4.11 eV for ZnAl2O4 and 2.79 eV for ZnGa2O4. With reference...
