Abstract

An ArF excimer laser MBE system specially designed for the deposition of ceramic thin films was used to construct atomi-cally defined epitaxial SrCuO2−x films. According to XPS analysis, Cu valence was evaluated to be 2+ in the film as-grown in the presence of 10−7 Torr NO2, but it was less than 2+ in the film prepared in the presence of 10−7Torr 02. In situ XPS depth analysis of as-grown SrCuO2−x film on SrTiO3 substrate revealed the band profile at the interface of the film and substarte. Ceramic superlattices composed of metallic SrCuO2−x (3∼8nm thick) and insulative SrTiO3 (8nm thick) were prepared by sequential heteroepitaxial growth.
