Abstract:The effect of an external electric field on the bandgap is observed for two proposed heterostructures graphitic carbon nitride-graphene-hexagonal boron nitride (g-C 3 N 4 /G/h-BN) in hexagonal stack (AAA) and graphene-graphitic carbon nitridehexagonal boron nitride (G/g-C 3 N 4 /h-BN) in Bernal stack (ABA). Their inter-layer distance, binding energy and effective mass has also been calculated. The structure optimization has been done by density functional theory (DFT) with van der Waals corrections. The inter-… Show more
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.
