Abstract:Raman spectroscopy has been used to examine diamond thin films produced by various CVD processes. The Raman spectra exhibit, features which suggest that the films are composites of diamond (sip)) and graphite -like (sp) bonding. A brief outline of Raman scattering from composites is presented. A first attempt at modeling these types of films using composites of diamond and graphite powders is reported. It is found that the Raman features associated with sp bonding in the films do not correlate well to features… 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.
