Stability of Near-Surface Nitrogen Vacancy Centers Using Dielectric Surface Passivation
Stability of Near-Surface Nitrogen Vacancy Centers Using Dielectric Surface Passivation
We study the photophysical stability of ensemble near-surface nitrogen vacancy (NV) centers in diamond under vacuum and air. The optically detected magnetic resonance contrast of the NV centers was measured following exposure to laser illumination, showing opposing trends in air compared to vacuum (increasing by up to 9% and dropping …
