MICROCLUSTER KINETICS ON SURFACES - A MONTE-CARLO SIMULATION WITH WAITING TIME

An improved algorithm of the continuous time Monte Carlo simulation in the lattice gas model based on the waiting time method was developed. This algorithm was applied to the computer simulation of micro-cluster kinetics upon annealing of the substrate. The new method works efficient in any temperature range. The numerical results explain the experimental features of the initial formation of small clusters and the subsequent resolution of unstable small clusters toward more stable large clusters during annealing. The thermal equilibrium property at high temperature is also discussed. © 1990.
