    • The adsorption geometries and their energetics for the Ag adatom on the faulted Si(111) 2 X 2 surface corresponding to the local structure in FHUC are almost the same as those on unfaulted Si(111) 2 X 2 surface (see Table IV), which implies that the diffusion processes of the Ag adatom are nearly identical on both surfaces.

    • note
    • The cohesive energy per atom of bulk Ag and the binding energy per atom of two-atom Ag cluster are calculated at 2.31 and 1.08 eV, respectively, which are much larger than the Ag binding energy on the H/Si(111) surface.
