Abstract
Work-function changes up to 0.6 eV were observed during the adsorption of W on a (110) W single-crystal surface for coverages below one monolayer. It is concluded that this is due to a varying structural arrangement of atoms in the outermost surface layer. Atoms in adpositions and ledge positions on their own lattice exhibit electric dipole moments causing work-function reductions with respect to the ideally flat surface.Keywords
