Dissociation of migrating particle from trap with long-range interaction field
Résumé
Some lattice defects, such as dislocations, interact with migrating species, e.g. vacancies, interstitial atoms and their clusters, via long-range strain fields. In this paper, an equation for the mean dissociation time of a migrating particle from a trap is derived in terms of the potential well function for the interaction energy. The distribution of dissociation times is studied by the Monte Carlo method, and the problem of particle exchange between spatially separated traps is considered.
