Electrochemical surfactant mediated growth of Ag on Au(111) was investigated experimentally using in situ scanning tunneling microscopy. Almost ideal layer-by-layer growth of Ag was obtained using 0.8 of a monolayer of Pb as a surfactant. Atomically flat epitaxial Ag thin films, 200 monolayer in thickness were grown on Au(111) using this technique. Energy dispersive X-ray analysis and Rutherford backscattering spectrometry showed no traces of Pb in the Ag layers grown.
