Abstract

Helium beam scattering has been used to study the growth and structures of ultra-thin metal films of Hg and Pb on Cu(001). In this article we principally describe adsorption of lead on a Cu(001) surface at 150 K. We observe a new ordered phase with square symmetry, and show that this new phase has a buckled superstructure. Subsequent adsorption of lead does not yield a Stranski-Krastanov growth, as observed for room-temperature adsorption, but a simultaneous multilayers growth. We summarize also our studies, reported in detail elsewhere, of mercury adsorption on Cu(001) and compare them with the results for lead on Cu(001).
