The epitaxial growth of Au on Pd(111) was studied by ion scattering/channeling, low-energy electron diffraction, and Auger analysis. A sharp transition from the pseudomorphic state to the state with misfit dislocations and strain was found. The critical thickness is 2.0±{}0.2 {} in this layer-by-layer growth system. The Au coverage dependence of the lattice constants for substrate and overlayer were measured in detail.
