Oscillations in photoemission from Cr/Fe/W(1 0 0) and Cr/W(1 0 0)

Abstract The electronic structure of thin Cr films on Fe/W(1 0 0) and W(1 0 0) has been studied by angle-resolved photoemission (PE). The data have been compared with results of density functional supercell calculations. A thickness-dependent PE intensity variation at the Fermi level is observed, which is assigned to Cr quantum-well-like states.
