Abstract:
1. Monoatomic and monocrystalline layer of diamond type carbon, said layer being characterized in that it is formed on the surface of a monocrystalline substrate of SiC and extends closely over the totality of said substrate area, said monocrystalline substrate of SiC being one of a thin layer of monocrystalline SiC in cubic phase β-SiC (100) formed on a platelet of Si or a platelet of monocrystalline SiC in hexagonal phase, said monoatomic and monocrystalline layer of diamond-type carbon consisting of a plane of carbon-carbon dimers of sp 3 configuration formed by transformation of the carbon hybridization on the last atomic layer of said SiC substrate, said layer of diamond-type carbon thereby extending over substantially the entire area of said substrate.
