Estimate of the potential relief (rippling) of a surface associated with adsorption of d-metal atoms on d-substrates

A cohesion approach developed previously by Davydov and Tikhonov to describe adsorption properties [Surf. Sci. 371, 157 (1997)] is used to calculate the ripple parameter Ω=E dif/E des (where E dif and E des are the activation energy of surface diffusion and the adsorption energy) for atoms of d-metals adsorbed on a W(110) surface. The results of the calculations show good agreement with the experimental data.
