| 英文摘要 | the growth of ag clusters on si(111)-7 x 7 surfaces was studied by scanning tunneling microscopy (stm), ultraviolet photoelectron spectroscopy, and x-ray photoelectron spectroscopy (xps). a shift in the ag 3d binding energy and a noticeable change in the valence-band structure reveal a significant modification of the electronic states of the si(111)-7 x 7 surface and the dispersed ag clusters, which had a strong dependence on the coverage of ag. furthermore, these ag clusters deposited on the si surface alter the behavior of oxygen adsorption on the si(111)-7 x 7 surface. as evidenced by xps, the presence of ag inhibits the adsorbed surface oxygen species, the ins-ins and ad-ins oxygen, in which "ad" denotes an o atom bonding on top of the si adatom and "ins" denotes an o atom inserted into a si adatom back bond. the stm and high-resolution electron energy loss spectroscopy results show that the ins-ins oxygen species are more significantly suppressed by the ag clusters compared to the ad-ins oxygen.
