Extending spin dephasing time of perfectly aligned Nitrogen-Vacancy centers by mitigating stress distribution on highly misoriented chemical-vapor-deposition diamond
T. Tsuji, T. Sekiguchi, T. Iwasaki +1
Extending the spin-dephasing time (T2*) of perfectly aligned nitrogen-vacancy (NV) centers in large-volume chemical vapor deposition (CVD) diamonds leads to enhanced DC magnetic se…
