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…
