Spin properties of shallow ensemble nitrogen-vacancy centers in a 12C-enriched diamond surface layer
Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a ^12 C-enriched diamond were investigated. NV spin properties, created by implantation of ^15 N ^+ ions with 2−5 keV energies and 1 × 10 ^11 −1 × 10 ^13 ions cm ^−2 doses, were evaluated by Rabi contrast, longitudinal...

| Summary: | Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a ^12 C-enriched diamond were investigated. NV spin properties, created by implantation of ^15 N ^+ ions with 2−5 keV energies and 1 × 10 ^11 −1 × 10 ^13 ions cm ^−2 doses, were evaluated by Rabi contrast, longitudinal relaxation time T _1 , and spin-spin relaxation time T _2 (spin echo). The optimal NV conditions, yielding high-quality NV spins’ properties, usable for nanoscale NV-NMR (nuclear magnetic resonance), were confirmed as 3 keV and 1−3 × 10 ^12 ions cm ^−2 doses with the lowest estimated value of AC magnetic field sensitivity as 44 nT Hz ^-1/2 . |
