Notes:
An au/Pd/Au(111) multilayer system grown by molecular beam epitaxy has been studied by high-resolution x-ray photoelectron spectroscopy. An analysis of the dependence of the relative intensity of the Au and Pd core-level XPS lines on the take-off angle indicates that the thickness of the Pd sandwhich layer is ∼5 monolayers. The photoelectron spectra show the presence of more than one chemical environment for each element and suggest that the core-level photoelectron spectra of Pd atoms in the interfacial layers and the inner layers of the Pd sandwich are split by ∼0.6 eV. The photoelectron spectra of the valence band show that the Pd sandwich retains the high density of states at the Fermi energy that is characteristic of Pd metal.
