Cerium oxide layers on Pt(111): a scanning tunneling microscopy study
Ultrathin epitaxial layers of cerium oxide A,ere prepared by oxidation of layers of an ordered Pt-Ce surface alloy on top of a Pt(111) single crystal. They consist of low-dimensional CeO2 islands. Atomically resolved scanning tunnel microscopy (STM) images indicate a surface structure of the fluorite-type CeO2(111) 1x1 phase and the presence of surface defects.
