Surfactant mediated electrochemical deposition of Ag on Au(111)

Electrochemical surfactant mediated growth of Ag on Au(111) was investigate d 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 thi ckness 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. (C) 1999 The Electrochemical Society. S1099-0062(98 )12-030-8.
