dc.description.abstractBy using first-principles pseudopotential method and density functional theory, the effect of external electric field on the work function changes of Ag, Au and K adsorbed on W(001) surface has been studied. We found that the work functions for all the systems changed linearly with the strength of external electric field. By comparison of the slopes of the work function change versus electric field, we have characterized the subtle difference between the bonding strengths of Ag-W(001) and Au-W (001). The results showed that the binding of Au-W(001) was slightly stronger than that of Ar-W(001).zh_CN
