## Description

- description: Controllability of nitrogen doping, types of nitrogen-related defects,
    and their charge states in homoepitaxial diamond (001) crystals were investigated.
    Nitrogen was incorporated uniformly into the crystals, with a concentration variation
    of less than 10%. About 70% of the total nitrogen was substitutional nitrogen
    in a neutral charge state Ns0. Hydrogen was incorporated at approximately the
    same concentration as nitrogen. Both NV and NVH centers were predominantly negatively
    charged defect structures, i.e., NV− and NHV− centers. The concentrations of NHV−
    centers were less than 5% of the total nitrogen concentration. Nitrogen concentration
    in diamond crystals was controlled by changing the N/C gas ratio over a wide doping
    range from 10 ppb to 10 ppm. Nitrogen incorporation efficiency was found to be
    (1.5 ± 0.5) × 10−4 in this study.
