Abstract:Abstract-Nanocomposite Nb-Al-N films prepared by magnetron sputtering have been studied. It has been found that, in the films, there are two stable crystalline structural states, namely, NbN z and B1-Nb 1 ⎯ x Al x N y O 1 -y , and an amorphous like component related to aluminum oxynitride upon reactive mag netron sputtering. It has been established that the substructure characteristics are sensitive to the current sup plied to an Al target and are related to the Knoop nanohardness and hardness, which change in… 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.
