Abstract
HG overlayers on Cu(100) and Cu3Au(100) have been investigated using low-energy electron diffraction (LEED) and angle-resolved photo-emission. Hg overlayers on both substrates adopt the structure of a square adlayer lattice. The resulting overlayers are a 20% expansion and a 9% compression of the Hg lattice parameter (with respect to bulk Hg) for the Cu(100) and Cu3Au(100) substrates respectively. Accompanying the change in the lattice parameter is a change in the electronic band structure. Results of Hg overlayers on several surfaces are shown to exhibit a relationship between the Hg lattice parameter and the electronic structure consistent with these results for Hg overlayers on Cu(100) and Cu3Au(100).Keywords
