## Description

- description: 'In this paper, the controllability of the nitrogen concentration in
    diamond was evaluated for two representative growth methods. One is the high-pressure
    high-temperature (HPHT) synthesis method and the other is chemical vapor deposition
    (CVD) method. The nitrogen concentration in the diamond was controlled by the
    ratio of nitrogen getter material in the metal solvent in the HPHT method, and
    by the gas flow ratio of carbon to nitrogen in the CVD method. The nitrogen concentration
    of HPHT-grown diamond decreased semi-logarithmically with increasing titanium
    or aluminum contents in the metal solvent. The nitrogen concentration of CVD-grown
    diamond increased linearly with increasing the flow rate ratio of nitrogen to
    carbon. The diamond crystals were irradiated with 2MeV  electron beams so that
    10% of the nitrogen at the substitutional site became NV− centers, and the negatively
    charged NV− centers were successfully formed preferentially. The T2 of these diamond
    crystals was inversely proportional to the nitrogen concentration. '
