Thermal Desorption of Ultrathin Ag Film, from a Pt(111) Surface, by AES

研究成果: 雜誌貢獻期刊論文同行評審

摘要

In the state of thermal equilibrium, the desorption of ultrathin Ag films from a Pt(111) surface is demonstrated to occur above 700 K and to be complete above 1000 K by Auger electron spectroscopy. The corresponding spectra are presented. The specimens were ultrathin Ag/Pt(111) films grown at 360 K with Ag coverage of 0.5, 1.0, and 1.5 of monolayers. The Pt(111) surface was cleaned by cycles of ion sputtering and annealing in an ultrahigh vacuum chamber. All spectra were collected with a surface science instrument of VG Microtech.
