| 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. |
