Abstract
The development of a new method for epitaxial growth of metals in solution is discussed and illustrated by proof-of-conceptresults. Cyclic voltammetry and scanning tunneling microscopy are employed to carry out and monitor a quasi-perfect, two-dimensional growth of up to 35 layers of Ag on Au 111 by repetitive galvanic displacement of an underpotentially deposited UPD Pb monolayer. The excellent quality of the deposit is manifested by an unchanged Pb UPD voltammetry and ascertained bya flat and uniform surface morphology maintained during the entire growth process.An X-ray photoelectron spectroscopy analysisfinds no traces of Pb in the Ag deposit.© 2005 The Electrochemical Society.
