چکیده انگلیسی
Photoemission experiments and theoretical calculations for the system Au-stepped W(1Â 1Â 2), have been done at submonolayer coverage region ranging from 0.1 to 0.9 monolayers, for different sample orientations relative to the photon polarization, i.e. parallel and perpendicular to the steps direction. Valence-band photoemission spectra of the Au/W(1Â 1Â 2) system demonstrate sharp angular dependent features at 4.5 and 0.3Â eV binding energies when the photon polarization is parallel to the steps direction. Density functional theory calculations were performed for the Au/W(1Â 1Â 2) system with monolayer and half monolayer Au coverages in order to assign the origin of these features.
