Characterization of CVD-grown NV-Diamond Material for Quantum Sensing Applications

Ensembles of nitrogen-vacancy (NV) centres in diamond are a leading platform for practical quantum sensors. However, the reproducible and scalable fabrication of CVD-grown, NV-diamond material with favorable properties is critical to realizing envisioned applications. This talk will discuss recent advances in the development of NV-diamond material for magnetic sensing and imaging applications, including improved NV-ensemble charge state under optical illumination, increased conversion of Ns into NV, and reduced crystal lattice strain inhomogeneity. Characterization techniques utilizing the NV centers themselves as probes play a crucial role in these efforts. The ability to produce diamond with reproducible properties will also be described.
