摘要:

金刚石中带负电荷的氮空位(NV-)中心在量子纳米计量学中有许多令人兴奋的应用,包括磁力测量、电学测量、温度测量和压力测量。实际上,单个NV中心可以测量局部电场的完整三维矢量或环境条件下单个基本电荷的位置。然而,为了实现这样的矢量测量,需要对中心的缺陷结构的取向的接近完整的知识。在这里,我们展示了一种光学检测磁共振(ODMR)技术,采用旋转的静电和磁场,精确地确定了该中心的主要和次要的三角对称轴的方向。因此,我们的技术是该中心现有矢量传感应用的推动者,也激发了多轴旋转传感,NV生长表征和金刚石晶体学的新应用。

英文摘要:

The negatively charged nitrogen-vacancy (NV-) centre in diamond has many exciting applications in quantum nano-metrology, including magnetometry, electrometry, thermometry and piezometry. Indeed, it is possible for a single NV- centre to measure the complete three-dimensional vector of the local electric field or the position of a single fundamental charge in ambient conditions. However, in order to achieve such vector measurements, near complete knowledge of the orientation of the centre's defect structure is required. Here, we demonstrate an optically detected magnetic resonance (ODMR) technique employing rotations of static electric and magnetic fields that precisely determines the orientation of the centre's major and minor trigonal symmetry axes. Thus, our technique is an enabler of the centre's existing vector sensing applications and also motivates new applications in multi-axis rotation sensing, NV growth characterization and diamond crystallography.
