FEATURE ARTICLEMesoscopic Metal Particles and Wires by ElectrodepositionReginald M. Penner*Department of Chemistry, UniVersity of California, IrVine, IrVine, California 92679-2025ReceiVed: August 18, 2001; In Final Form: December 12, 2001The electrodeposition of metal onto a low energy electrode surface like graphite or H-terminated siliconproduces mesoscopic metal particles that are broadly distributed in diameter. Broad size distributions areobserved even in cases where the nucleation of metal is temporally controlled. For this reason, electrodepositionhas been infrequently used as a means for obtaining metal nanostuctures. The central problem is the diffusional“cross-talk” that exists between neighboring metal nanostructures on the electrode surface. Evidence for thisdiffusional interparticle coupling is encoded into particle size and position distributions obtained fromexperimental data and from Brownian Dynamics computer simulations of nanostructure growth. Diffusionalcross-talk b...
