Title: Nucleation and growth of metal on nanoelectrodes
Abstract: Three-dimensional nucleation and growth on active surface sites are important initial stages of the electrodeposition of Electrochemical studies of these processes are greatly by the formation of multiple crystals interacting with each We investigated Ag electrodeposition on the surface of nanometer-sized Pt electrodes and measured the kinetics of individual Ag crystals by a combination of and atomic force microscopy (AFM). Basic including the number of surface active sites, the kinetic lag and the number of growing nuclei, were directly accessed from transients and in situ AFM imaging. The existence of a single site on the surface of a 50 nm electrode persisting through several deposition/stripping cycles has been demonstrated.
