Spin-resolved photoemission from epitaxial Au layers on Pt(111): Coverage dependence of the bandstructure and evidence of surface resonances

Abstract: Au/Pt (111) has been studied by spin-, angle-and energyresolved photoemission with normal incident circularly polarized synchrotron radiation of BESSY and normal photoelectron emission for different Au coverages. The prepared layers were characterized by LEED and Augerelectron spectroscopy and turned out to grow up two dimensional and epitaxially. In the photoemission experiments the development of the 3-dimensional bandstructure in the A-direction could be observed. For a coverage of 2.6 layers the highest oc… Show more

“…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.…”
