Abstract
A theoretical model is proposed for understanding the effect of H adsorption on the displacive transition of the W(001) surface. The coupling of the H adatoms to the substrate distortion leads to an enhancement of the displacive transition and a change in the overall symmetry. This is consistent with the features observed in low-energy electron diffraction for the H/W(001) chemisorption system.Keywords
