Web1 okt. 2024 · Nitrogen-vacancy (NV) colour centres in diamond have attracted extensive attention in quantum precision measurement, computation and communication. In these … WebWe will now describe the mechanism by which the NV spin state polarizes into m_S=0 under optical excitation, and how the NV fluorescence depends on the spin state. On the … Web25 mrt. 2024 · External magnetic field (\({B}_{0}= 7.5~\mbox{mT}\)) is used to provide the NV centers with a known magnetic bias. The device under test (DUT) is placed under the diamond. The CVD diamond chip used in our experiment was a (100) oriented plate such that the normal vector to the bottom surface (sensing plane) was parallel to the [100] … baian springs
