Webb28 feb. 2011 · We present a procedure that makes use of group theory to analyze and predict the main properties of the negatively charged nitrogen-vacancy (NV) center in … 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 irradiation, including electrons, protons, neutrons, … Visa mer 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 … Visa mer 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 contain ms = ±1 spin states, in which the two electron spins are aligned (either up, such that ms = +1 or down, such that ms = -1), … Visa mer Optical spin manipulation Optical transitions must preserve the total spin and occur only between levels of the same total spin. Specifically, transitions between the ground … Visa mer 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 … Visa mer 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 … Visa mer NV centers emit bright red light ( E→ A transitions), if excited off-resonantly by visible green light ( A → E transitions). This can be done … Visa mer 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 use of spectral shape for sensing those perturbation is impractical, as the … Visa mer
