Relaxation kinetics in two-dimensional structures
arXiv:cond-mat/0306419 · doi:10.1103/PhysRevB.68.195407
Abstract
We have studied the approach to equilibrium of islands and pores in two dimensions. The two-regime scenario observed when islands evolve according to a set of particular rules, namely relaxation by steps at low temperature and smooth at high temperature, is generalized to a wide class of kinetic models and the two kinds of structures. Scaling laws for equilibration times are analytically derived and confirmed by kinetic Monte Carlo simulations.
