Impact of irradiation conditions on the magnetic field sensitivity of spin defects in hBN nano flakes
Saksham Mahajan, Ravi Kumar, Aferdita Xhameni +8
We study centres generated by helium focused ion beam (FIB) irradiation in thin (70 nm) hBN nanoflakes, in order to investigate the effect of implantation…

Stability of near surface nitrogen vacancy centers using dielectric surface passivation
Ravi Kumar, Saksham Mahajan, Felix Donaldson +8
We study the photo-physical stability of ensemble near-surface nitrogen vacancy (NV) centers in diamond under vacuum and air. The optically detected magnetic resonance contrast of…
