Robust magnetometry with single nitrogen-vacancy centers via two-step optimization
Robust magnetometry with single nitrogen-vacancy centers via two-step optimization
Shallow nitrogen-vacancy (NV) centers are promising candidates for high-precision sensing applications; these defects, when positioned a few nanometers below the surface, provide an atomic-scale resolution along with substantial sensitivity. However, the dangling bonds and impurities on the diamond surface result in a complex environment which reduces the sensitivity and is …
