“…The shoulder S can be interpreted as corresponding to an anti-bonding orbital and peak O as corresponding to a bonding orbital. This interpretation is supported by the fact that both for Au [23] and for Si 1-24] electronic density exists in this energy range. For Au(111) a A34, 5 band lies 1.5 eV below the first levels corresponding to the peaks A and B.…”

“…1. Peak A and peak B agree in their energetic positions and spin polarization signs with two peaks for two dimensionally grown Au/Pt(lll) [18] and a Au(lll) single-crystal [23]. For a Au(111) crystal these peaks are due to transitions from the d-derived first A a, 5 and Aa6 bands below EF into the free-electron-like final band.…”

“…For a Au(111) crystal these peaks are due to transitions from the d-derived first A a, 5 and Aa6 bands below EF into the free-electron-like final band. For Au/Pt(lll) and a Au(111) single crystal only two tran-sitions are visible for our geometry at a photon energy of 15eV [18,23]. The existence of the additional structures can be understood by means of the scheme [22] in the lower part of Fig.…”

Abstract. Au on Si(111) in the 1 x 1 structure for different coverages and in the ~/3 x ~/3R30 °, and the 5 x 1 reconstructions has been studied by means of spin-, angle-, and energy-resolved photoemission. The photoemission studies were performed at normal incidence of the circularly polarized light and normal electron emission. In addition to Au-and Si-derived peaks other highly spin-polarized peaks are observed for a coverage of 8 Au layers grown at room temperature. In keeping with previous work these peaks are interpreted as silicide peaks. The spin polarization of these peaks gives clues concerning the levels involved in the silicide formation. For a coverage of 16 Au layers on Si(111) in the 1 x 1 structure the photoemission spectra are similar to the spectra of a Au(111) crystal, but also show a contribution of the silicide peaks. For lower coverages the spectra are nearly independent of the structure (1 x 1, ]/~ x V~R30 ° or 5 x 1) and already show peaks other than the pure Au-and Si-derived peaks. The Auger signal, however, does not show contributions in addition to the pure Si signal.

High-resolution normal photoemission (ARPE) spectra have been recorded for Cu3Au(l 1 I) with the use of polarized synchrotron and rare-gas resonance radiation in the photon energy range from 9 to 27 eV. It is for the first time that dispersions of the gold-like bands have been found experimentally. Using a fully relativistic layer-KKR photoemission formalism, occupied and unoccupied bands as well as one-step-model photoemission spectra have been calculated. The comparison of calculated spectra with experimental ones and the observation of direct-transition resonances upon photon energy near the Brillouin zone-center reveal a shift of the unoccupied ground-state bands by about +2.5 eV (self-energy shift). The direct-transition structures in the experimental spectra have been exploited to determine the dispersions of the occupied bands along the [ 11 I] direction (A line in k space). In order to determine the wave vector of the experimental direct transitions we used as final state that calculated unoccupied band along [ 1 1 I], which also exists in pure copper and gold up to about 20 eV above the Fermi energy ("unfolded" band structure), shifted by + 2.5 eV. The experimental occupied bands with Cu character are in very good agreement with theory after shifting the latter by about 0.3 eV to lower energy, whereas somewhat bigger discrepancies exist for the gold-like bands.
