Abstract:Raman spectroscopy was used to study the features of the electron-phonon interaction in thin carbon films that are capable of low-field emission of electrons. It was found that in the Raman spectra of samples with this ability the characteristic peaks of carbon were almost completely suppressed, and also a wide photoluminescence band could be present. At the same time, the Raman spectra of non-emitting samples had the form typical of graphite-like carbon spectrum. This observation is in accordance with the two… 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.
