Abstract
CuYO2, doped with calcium, is a low-mobility p-type semiconductor. From photoelectrochemical measurements it is found that the valence band edge is 5.3 eV below the vacuum level, typical for oxides with a metal-3d valence band. The lowest bandgap is 1.20 eV and the transition is indirectly allowed. An optical transition at 3.60 eV indicates an oxygen-2p valence band at 7.7 eV below vacuum. The results are discussed with the help of a simplified band scheme.
