WebDec 26, 2024 · We investigate the fundamental mechanism of spin-phonon coupling in the negatively charged nitrogen-vacancy center (NV −) in diamond in order to calculate the … The nitrogen-vacancy center is a point defect in the diamond lattice. It consists of a nearest-neighbor pair of a nitrogen atom, which substitutes for a carbon atom, and a lattice vacancy. Two charge states of this defect, neutral NV and negative NV , are known from spectroscopic studies using optical absorption, … See more The nitrogen-vacancy center (N-V center or NV center) is one of numerous point defects in diamond. Its most explored and useful property is its photoluminescence, which allows observers to read out its spin-state. The NV … See more The NV center has a ground-state triplet ( A), an excited-state triplet ( E) and two intermediate-state singlets ( A and E). Both A and E … See more Optical spin manipulation Optical transitions must preserve the total spin and occur only between levels of the same total spin. … See more The spectral shape and intensity of the optical signals from the NV centers are sensitive to external perturbation, such as temperature, strain, electric and magnetic field. However, the … See more Nitrogen-vacancy centers are typically produced from single substitutional nitrogen centers (called C or P1 centers in diamond literature) by irradiation followed by annealing at temperatures above 700 °C. A wide range of high-energy particles is suitable for such … See more NV centers emit bright red light ( E→ A transitions), if excited off-resonantly by visible green light ( A → E transitions). This can be done with convenient light sources such as argon or krypton lasers, frequency doubled Nd:YAG lasers, dye lasers See more The microscopic model and most optical properties of ensembles of the NV centers have been firmly established in the 1970s based on the optical measurements combined with uniaxial stress and on the electron paramagnetic resonance. However, a minor … See more
