英文摘要The growth and oxygen adsorption of Ag on an ordered Al2O3 film, prepared on Mo(110) substrate, have been studied in situ under ultrahigh-vacuum condition using X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and low-energy electron diffraction. The results show that Ag particles/clusters are formed on alumina film at initial coverages, and the binding energy of the Ag 3d(5/2) line for Ag clusters is higher than that of bulk Ag, arisen from the size effect. Exposure of Ag clusters to similar to 10(-7) mbar O-2 leads the clusters to spreading over the substrate. It is of importance in many application areas to understand the origin of oxygen-induced metal-cluster changes in morphology and size.
