Abstract
We report ultraviolet (uv) Raman scattering studies of hydrogen-free, diamondlike amorphous carbon thin films with a wide range of tetrahedr al bonding. The uv Raman spectra are shown to provide direct evidence for the presence of sp(3)-bonded C atoms in these materials. The exper imental results are found to be in excellent agreement with theoretica l predictions and contribute to an improved understanding of the mecha nism by which the diamondlike fraction develops within the amorphous c arbon network.
