Diffusion and growth of metal clusters in nanocomposites: a Kinetic Monte Carlo study
metal clusters, bulk and surface diffusion, agglomeration, Kinetic Monte Carlo
2011/9/2
Nobel metals that are deposited on a polymer surface exhibit surface diffusion and diffusion into the bulk. At the same time the metal atoms tend to form clusters because their cohesive energy is abou...
