Abstract
⺠SrTi(1 â x)FexO(3 â δ) (0 â¤Â x â¤Â 1) perovskite compounds have been prepared by a high temperature solid state reaction process. ⺠The surface state and band structure of the STF have been probed by X-ray and ultraviolet photoelectron spectroscopy. ⺠XPS results showed that the iron present in the STFx is composed of a mixture of Fe3+ and Fe4+. ⺠With increasing iron doping, the amount of Fe3+ and Fe4+ increased significantly and the oxygen lattice decreased.
