Abstract

Monte Carlo simulations of the kinetics of migration and coalescence of nm-sized metal particles on a uniform surface and a surface with traps in the physically reasonable case when the diffusion coefficient of particles varies inversely as the fourth power of the particle size are presented. The Monte Carlo kinetics are demonstrated to be in good agreement with the mean-field results. The size distribution of particles is found to be nearly symmetrical with respect to the average value.
