Microwave-assisted spectroscopy technique for studying charge state in nitrogen-vacancy ensembles in diamond

D. P. L. Aude Craik, P. Kehayias, A. S. Greenspon +7

We introduce a microwave-assisted spectroscopy technique to determine the relative concentrations of nitrogen vacancy (NV) centers in diamond that are negatively-charged (NV${}^{-}$)…
