Dissociated vacancies and screw dislocations in MgO and UO2: atomistic modeling and linear elasticity analysis
Abstract Understanding the effect of dislocations on the mass ngetikin transport in ionic ceramics is important for understanding the behavior of these materials in a variety of contexts.In particular, the dissociated nature of vacancies at screw dislocations, or more generally, at a wide range of low-angle twist grain-boundaries, has ramifications
