2D (< 10 nm) sp3-C-rich carbon materials, possibly hydrogenated: A review

While graphene has held the center stage in nanocarbon material research since its isolation 2004, less attention been paid to nanometer-thick carbon films which at least part of atoms are sp3-hybridized, whatever crystallographic structure. However, because their composition, structure, physical and chemical properties, those nanomaterials exhibit competitive features that should be considered for development future sustainable technologies based on 2D materials. The purpose this review is provide a snapshot main advances synthesis sub-10 nm thick sp3-C-rich films, include amorphous hydrogenated or not, nanocrystalline diamond graphane, diamanes diamanoids. Physical properties applications (i.e. existing potential) also highlighted.
