Abstract

The growth, ordering, and energetics of Hg overlayers on Cu(O01) have been studied using atom beam scattering, LEED and angle-resolved photoemission. Two stable ordered phases have been identified: one phase is a c(2↑2) and the other phase is a higher density square lattice which has a coincidence c(4↑4) structure. A phase diagram has been determined using LEED and atom beam diffraction data for surface temperatures between 180 and 330 K. ABS data suggest out that there is a narrow coexistance region between these two phases. The isosteric heat of adsorption has been determined as a function of coverage.
