IThere is a great effort to achieve electron emission from chemical vapor deposited (CVD) polycrystalline diamond film. This is because diamond possesses high chemical stability, extraordinary hardness, high thermal conductivity, high melting temperature, and low electron affinity [ll. In this report we present a method for fabricating a patterned diamond tip array. Selective deposition of CVD diamond film is an important technique in the fabrication of diamond electronic devices. We have used silicon oxide to block the lateral growth of diamond to selectively grow a diamond field emitter array.
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.
