Metal Heterodiffusion on Metallic Surfaces: Case of Pb on Cu,nd exchange with surface Cu atoms. Increasing the Pb coverage towards θ., we observe that Pb diffusion depends strongly on θ, evidencing the influence of Pb-Pb interactions. The appearance of ordered structures markedly affects the chemical diffusion coefficient. Above θ., the structure and morphology of the wetting layer influences Pb diffusion.

Surface Diffusion Near Phase Transitions,cent work reviewed here will stimulate further work in this and related fields. The main emphasis of this article is on transport phenomena at or near equilibrium, i.e., on diffusion of particles within (nearly) equilibrated adsorbed monolayers on homogeneous surfaces.
