Theoretical and numerical analysis is presented for kinetics of impurity segregation at the boundaries of a thin layer of substance dividing two different materials. Time dependences of boundary impurity concentrations and concentration profiles within the film have been obtained. Depending on the energy of impurity interaction with the boundaries and the temperature, some criteria were established to predict probable realization of segregation process. The time of exhausting of areas adjusting segregation layers and the width of the exhausted zone near the boundaries was evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
