Photoemission from surface-localized structures on vicinal surfaces: Initial- or final-state superlattice effect?
(2005) In Journal of Electron Spectroscopy and Related Phenomena 144-147. p.625-628- Abstract
- Strong superlattice effects are reported on E(k(vertical bar vertical bar)) band dispersions measured by angle-resolved photoemission on W(3 3 1) and W(5 5 1), and graphene nanostripes on Ni(7 7 1). A splitting of the dispersions with reciprocal superlattice vector G = 2 pi/L is observed for a surface resonance on W(3 3 1) and W(5 5 1) and for pi-states of graphene/Ni(7 7 1). Photon-energy-dependent measurements and comparison to LEED show that electrons are confined to the one-dimensional terraces and stripes, respectively, and that the observed superlattice effects are due to diffraction in the final state of the photoemission transitions.
