The problem of edge-atom depression on a Cu{410} surface

Calculations based on our modified point-ion electrostatic model of the multilayer relaxation expected on a stepped Cu{410} surface predict an average edge-atom depression normal to the surface of 0.15 Å. This value is in good agreement with the results obtained in another laboratory with ion-scattering experiments yielding 0.18±0.05 Å, but disagrees with the results obtained elsewhere with kinematic LEED analysis, which revealed no measurable edge-atom depression. © 1987.
