First-principles molecular-dynamics calculations have been used to calculate the formation energy of the lowest-energy As interstitial configuration relative to the formation energies of As antisites and Ga vacancies in As-rich GaAs, and to identify and study the properties of energetically favorable complexes containing one As antisite and one As interstitial. It is suggested that the electronic and optical properties of the antisiteinterstitial complexes match the properties of the defects responsible for the dominant donor band in some samples grown around 350°C.
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.
