Spin properties of shallow ensemble nitrogen-vacancy centers in a 12C-enriched diamond surface layer

Year: 2025

Type: article

Abstract: Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a 12C-enriched diamond were investigated. NV spin properties, created by implantation of 15N+ ions with 2−5 keV energies and 1 × 1011−1 × 1013 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 × 1012 ions cm−2 doses with the lowest estimated value of AC magnetic field sensitivity as 44 nT Hz-1/2.
