We perform two-Gaussian and two-Lorentzian peak fits for Raman spectral data corresponding to samples of thin-film carbon found in the scientific literature. We find that the “goodness-of-fit,” as determined through an evaluation of the root-mean-square-error, is best for the two-Gaussian peak case over most of the thin-film carbon genome, except for the graphitic carbon and ta-C:H regions. We speculate that this is related to the lower levels of disorder present within the graphitic carbon and ta-C:H regions.
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.
