Abstract:Surface hydrogenation is revealed to be an effective way to achieve phase engineering in group V MSi2N4 materials, which undergo structural transitions in both central MN2 and surface SiN layers.
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.
