| Abstract
| - An adaptation of the Brownian dynamics simulation method has been used to model the growth of a particular200-particle ensemble of silver nanoparticles. This ensemble of particles was randomly positioned on anelectrode of total area 1.0 × 10-9 cm2, and these particles possessed a significant size distribution. The growthof this distribution was investigated at overpotentials ranging from −1 mV to −200 mV. These simulationsdemonstrate that reduced rates of electrodeposition effectively reduce the particle size dispersion present inan ensemble of particles. The beneficial effect of “slow growth” is brought about by the elimination or reductionof the diffusional coupling present between neighboring particles on the electrode surface.
