Abstract
Section titled āAbstractāThe sensitivity of magnetic and electric field sensors based on\nnitrogen-vacancy (NV) center in diamond strongly depends on the available\nconcentration of NV and their coherence properties. Achieving high coherence\ntimes simultaneously with high concentration is a challenging experimental\ntask. Here, we demonstrate that by using a high-pressure, high-temperature\ngrowing technique, one can achieve nearly maximally possible effective\ncoherence T2* times, limited only by carbon nuclear spins at low nitrogen\nconcentrations or nitrogen electron spin at high nitrogen concentrations.\nHahn-echo T2 coherence times were also investigated and found to demonstrate\nreasonable values. Thus, the high-pressure, high-temperature technique is a\nstrong contender to the popular chemical vapor deposition method in the\ndevelopment of high-sensitivity, diamond-based sensors.\n
