Changes in the growth mode of electrodeposited silver layers : Surface rearrangements induced by the presence of lead adatoms

The surface characteristics of Ag electrodeposits prepared on polyfaceted Pt(sc) electrodes have been followed through complete Pb upd/stripping voltammetry. The growth mode of Ag overlayers at constant temperature depends on both the cathodic electrodeposition overvoltage and the silver ion concent...
