ATOMIC-SCALE MODELING OF RADIATION-DAMAGE BY SAS

Stochastic annealing simulations provide a way of exploring the evolut ion of displacement damage created by irradiation over large time and distance scales while retaining explicit information on the spatial di stribution of individual defects. In this article, the various stages of defect production in displacement cascades and the models that are applicable at each stage are discussed. The role of stochastic anneali ng simulations as a link between molecular dynamics and reaction-rate theory is illustrated by simulations of defect production in cascades in copper.
