Electron-Nuclear Coherent Coupling and Nuclear Spin Readout through Optically Polarized VB- Spin States in hBN

Fadis F. Murzakhanov et al.

Summary: In this study, we demonstrated the coherent coupling of negatively charged boron vacancies (V-B(-)) with surrounding nuclei in hexagonal boron nitride (hBN), which meets the basic requirements for quantum technology applications. We successfully achieved the readout of the V-B(-) spin coherence using various techniques and showed the characteristics of elongation of coherence time and modulation of Hahn-echo decay. Additionally, the DFT calculation confirmed the confined electron-nuclear coupling in the defective layer.

Generation of Optically Addressable Spin Centers in Hexagonal Boron Nitride by Proton Irradiation

F. F. Murzakhanov et al.

Summary: This study investigates the possibility of creating defects with spin-dependent fluorescence in a van der Waals material, hexagonal boron nitride (hBN), by irradiating it with high-energy protons (E-P = 15 MeV). The results from microphotoluminescence and electron paramagnetic resonance methods demonstrate the emergence of boron vacancies in the negatively charged state (V-B(-) centers) following irradiation, with optically induced population inversion in the ground triplet spin state (S = 1).

Spin defects in hBN as promising temperature, pressure and magnetic field quantum sensors

Andreas Gottscholl et al.

Summary: Spin defects in two-dimensional materials, such as negatively charged boron vacancies in hexagonal boron nitride, are demonstrated as sensors for magnetic fields, temperature, and pressure. These defects show high-spin triplet ground state and bright spin-dependent photoluminescence, making them potential candidates for quantum sensing applications. The frequency shift in optically detected magnetic resonance measurements is sensitive not only to static magnetic fields, but also to temperature and pressure changes, related to crystal lattice parameters. Spin-rich hexagonal boron nitride films may find applications as intrinsic sensors in heterostructures made of functionalized 2D materials.
