Abstract:In this paper, based on molecular dynamics simulation method, the authors construct a graphene flake sliding on a suspended graphene layer which is anchored on a bed of springs. This graphene-spring system provides an ideal model to replace the multilayer graphene under the top layer. We firstly mimic different layers of suspended graphene through changing the stiffness of spring bed; then the contributions of Van der Waals force of the tip and elastic deformation of the top layer supported by spring bed to fr… 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.
