摘要:钻石中NV中心的类似物中的3 c-SIC中的氮 - 胶囊(NV)中心最近成为具有竞争性能和显着技术优势的固态量子。结合了第一原理计算和磁共振光谱,我们在其磁光特性中提供了详尽的见解。By applying resonantly excited electron paramagnetic resonance spectroscopy, we identified the zero-phonon absorption line of the 3 A 2 → 3 E transition at 1289 nm (within the telecom O- band) and measured its phonon sideband, the analysis of which reveals a Huang-Rhys factor of S = 2.85 and a Debye-Waller factor of 5.8 %.发现低温自旋晶格松弛时间异常长(4 K时T 1 = 17 s)。所有这些属性使NV在3 C -SIC中成为量子应用的强大竞争者。此外,在4K至380K范围内,零场拆分的强烈变化允许其应用于纳米级的热感应。
