摘要：

Various interface structures formed between Si(111) and a thick Ag overlayer are investigated by grazing-incidence x-ray diffraction. The (7 x 7) reconstruction of Si(111) is preserved under a room-temperature deposited Ag film. Upon annealing to 250-degrees-C the interface becomes (1 x 1). This is contrasted by the (square-root 3 x square-root 3)R30-degrees structure formed by annealing a thin Ag film on Si(111). By depositing a thick Ag film on this (square-root 3 x square-root 3)R30-degrees Ag/Si(111) surface at room temperature, the (square-root 3 x square-root 3)R30-degrees reconstruction is suppressed.
