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 (sp³) and graphite-like (sp⁴) 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 sp²bonding in the films do not correlate well to features exhibited by microcrystalline graphite.
