Cesiation of W(001): Work function lowering by multiple dipole formation

Journal Article · · Phys. Rev. Lett.; (United States)
Rigorous, self-consistent, all-electron, full potential linearized augmented plane wave studies reveal that the lowering of the W(001) work function upon cesiation arises from a complex multiple dipole formation mechanism: Essentially, Cs forms a metallic overlayer with its valence electrons strongly polarized and its 5p semicore shell polarized oppositely.
