  • Characterization of defects in monocrystalline CVD

    2003-3-1 · Monocrystalline CVD films can be easily grown on monocrystalline diamond substrates. However, such samples were not studied here because many ESR centers are present in CVD diamond in small concentrations (<1 ppm) and therefore can be masked by background signals from the substrate.
