Abstract
Ag/Si(111) has been studied by spin-, angle-, and energy-resolved photoemission with circularly polarized radiation from the Berliner Elektronenspeicherring-Gesellschaft für Synchrotionstrahlung (BESSY) for the 1×1 and (√3×√3 )R30° surfaces at a converage of 0.5 monolayer. The spin-resolved photoemission data were obtained for normal incidence of the light and normal emission of the photoelectrons. For both the 1×1 and (√3×√3 )R30° structures we find no dispersion in the Ag photoelectron peaks depending on K∥ and K⊥. For the 1×1 structure and for photon energies between 20 and 24 eV, we observe an additional Ag photoelectron peak at about 1 eV higher binding energy which results from a d-level splitting due to Ag-Ag interaction. This peak is absent for the (√3×√3)R30° phase, which demonstrates that the Ag-Ag neighbor interaction is negligible. This supports the models that do not imply Ag-Ag interaction for the Ag adsorption in the (√3 × √3 )R30° phase.
