The nitrogen-vacancy (NV) center in diamond has been found to be a powerful tool for various sensing applications. In particular, in ensemble-based sensors, the main “workhorse” so far has been optically detected electron resonance. Utilization of the nuclear spin has the potential to significantly improve sensitivity in rotation and magnetic field sensors. Ensemble-based sensors consume a substantial amount of power, leading to noticeable heating of the diamond and thus requiring an understanding of temperature-related shifts. In this paper, we provide a detailed study of the temperature shift of the hyperfine components of the NV center.

NV中心基态哈密顿量核项的温度漂移率

已经发现金刚石中的氮空位（NV）中心是用于各种传感应用的强大工具。特别是在基于集合体的传感器中，到目前为止，主要的“主力马”已经通过光学方式检测到电子共振。利用核自旋有可能显着提高旋转传感器和磁场传感器的灵敏度。基于集合体的传感器消耗大量功率，从而导致钻石明显发热，因此需要了解与温度有关的偏移。在本文中，我们提供了对NV中心超精细组件温度漂移的详细研究。
