摘要：

The oxidation of Cu(100)-Fe surfaces was studied using XPS. Surfaces containing 0-10 ML of iron were oxidised at room temperature exposing 2 Pa . s of oxygen. For all surfaces evidence for Fe2O3 was found. For surfaces containing more than 2 ML of iron, metallic Fe2p3/2 and 2p1/2 signatures were observed. The analysis of the change of the 2p peak shape of a surface containing 1 ML of Fe as a function of different oxygen coverages showed that oxidation proceeds via an intermediate containing both Fe2+ and Fe3+.
