Abstract
We investigate the vacancy distribution in A/B phase-separating (111) multilayer at low temperature, about 0.25Tc. Three-dimensional kinetic Monte Carlo simulations with a vacancy-diffusion mechanism are performed. The atomic diffusion model accounts for the energy differences in formation ΔEf and in migration ΔEm of vacancies in the two terminal phases. We show that the migration term Δmf may lead to long lived transient vacancy distributions. The latter are interpreted by using a modified kinetic mean-field approach that accounts for some local dynamic correlations.
