摘要：
Initial stages of Ag atoms adsorption on Si(111)-7 x 7 surface were studied by first-principles calculations. The results showed that the most stable adsorption position for a single Ag atom is at S sites, which are almost in the middle between H-3 and B-2 high coordination sites. When two single Ag atoms are adsorbed on a Si half unit cell, they prefer to adsorb on the two closest S sites and form weak Ag-Ag bond.
