The features and advantages of multicomponent compound cathodes for vacuum electronic devices are discussed. The effects of recent experimental data on the effective work function of a composite cathode with cubic boron nitride as the principal phase, are presented. Methods to reduce the work function of new materials so as to develop high(er) efficiency cathodes, are proposed.
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.
