Abstract
The adsorption and the surfactant effect of Sb on the Ag(100) surface are studied using first-principIes calculations. Our calculated result s show that the pre-adsorbed Sb atoms act as nucleation centres for th e deposited Ag atoms, and surface-substitutional Sb atoms repel on-fee -site Ag atoms nearby. We suggest that the Sb repulsion network reduce s the Ag-adatom mobility and leads to a high density of Ag islands whi ch improve the smoothness of the layer-by-layer growth.
