Issue Date: | 2022 | Publisher: | AMER PHYSICAL SOC | Source: | Physical Review Applied, 18 (2) (Art N° 024079) | Abstract: | While nitrogen-vacancy (N-V & minus;) centers have been extensively investigated in the context of spin -based quantum technologies, the spin-state readout is conventionally performed optically, which may limit miniaturization and scalability. Here, we report photoelectric readout of ground-state cross-relaxation fea-tures, which serves as a method for measuring electron-spin resonance spectra of nanoscale electronic environments and also for microwave-free sensing. As a proof of concept, by systematically tuning N -V centers into resonance with the target electronic system, we extract the spectra for the P1 electronic spin bath in diamond. Such detection may enable probing optically inactive defects and the dynamics of local spin environment. We also demonstrate a magnetometer based on photoelectric detection of the ground -state level anticrossings (GSLACs), which exhibits a favorable detection efficiency as well as magnetic sensitivity. This approach may offer potential solutions for determining spin densities and characterizing local environment. <comment>Superscript/Subscript Available</comment | Notes: | Zheng, HJ (corresponding author), Johannes Gutenberg Univ Mainz, D-55128 Mainz, Germany.; Zheng, HJ (corresponding author), Helmholtz Inst, GSI Helmholtzzentrum Schwerionenforsch, D-55128 Mainz, Germany.; Zheng, HJ (corresponding author), Chinese Acad Sci, Beijing Natl Lab Condensed Matter Phys, Beijing 100190, Peoples R China.; Zheng, HJ (corresponding author), Chinese Acad Sci, Inst Phys, Beijing 100190, Peoples R China. zheng@uni-mainz.de |
