Nanocrystalline sp 2 and sp 3 carbons: CVD synthesis and applications

The design and production of innovative materials based on nanocrystalline sp 2- and sp 3-coordinated carbons is presently a focus of the scientific community. We present a review of the nanostructures obtained in our labs using a series of synthetic routes, which make use of chemical vapor deposition (CVD) techniques for the selective production of non-planar graphitic nanostructures, nanocrystalline diamonds, and hybrid two-phase nanostructures.
