Window into NV center kinetics via repeated annealing and spatial tracking of thousands of individual NV centers

open access: yesPhysical Review Materials, 2020
Knowledge of the nitrogen-vacancy center formation kinetics in diamond is critical to engineering sensors and quantum information devices based on this defect. Here we utilize the longitudinal tracking of single NV centers to elucidate NV defect kinetics during high-temperature annealing from 800-1100 $^\circ$C in high-purity chemical-vapor-deposition ...
