Research on weak magnetic field detection using NV– centers in diamond has been intensively studied in the world. Controlling the nitrogen concentration [N] in the diamond crystal in the concentration range of 1-30 ppm is required to obtain higher magnetic sensitivity. In this study, nitrogen-doped free-standing crystals were grown by microwave-plasma chemical vapor deposition method, and the type and concentration of nitrogen-related point defects formed in these free-standing crystals were characterized by using various evaluation methods.
