Further hydrogen adsorption onto the hydrogen-covered W(110)-(1× 1) phase results in the reconstruction of the surface hydrogen layer with a sizable corrugation in one direction. The wave vector for the superstructure is found to be very close to the nesting vector of the Fermi surface. Upon the rearrangement, the characteristic surface phonon anomaly becomes much more pronounced. The further pronounced anomaly can be explained by the modification of the electronic band around the Fermi level, concerted with the imposed superperiodicity. [DOI: 10.1380/ejssnt.2006.548]
