Isotopic control of the boron-vacancy spin defect in hexagonal boron nitride

T. Clua-Provost, A. Durand, Z. Mu +12

We report on electron spin resonance (ESR) spectroscopy of boron-vacancy (V${}_{\text{B}}^{-}$) centers hosted in isotopically-engineered hexagonal boron nitride (hBN) crystals. We first…
