Measurements of work function changes (ΔΦ) and Auger Electron Spectroscopy were used for investigation of very thin silver layer adsorption on the (111) face of copper crystal. At room temperature the layer-by-layer growth was observed while at temperatures above 850 K ΔΦ and the Auger peak height kinetics indicated the presence of silver diffusion to the surface layer of the copper sample.
