  • Nanocrystalline diamond - ScienceDirect

    Nanocrystalline diamond was a term initially given to thin film diamond of poor quality. In the earlier days of diamond growth, when CVD reactor design was in its infancy and nucleation densities were very low, nanocrystalline diamond was a name given to thin diamond films which generally had low quality.
