- An electrodeposition technique is described that produces atomically ßat epitaxial
metal overlayers of quality similar to that obtained by ultrahigh vacuum
techniques at elevated temperature. In this approach, a metal of interest such
as silver is co-deposited with a reversibly deposited mediator metal. The mediator is periodically deposited and stripped from the surface, and this serves to signiÞcantly increase the density of two-dimensional islands of silver atoms, promoting a layer-by-layer thin-Þlm growth mode. In situ scanning tunneling microscopy was used to demonstrate the growth process for the heteroepitaxial system silver/gold （111） with either lead or copper as the mediator.
