论文摘要
在六角硼（HBN）中宿主的光学活性自旋缺陷是开发二维（2D）量子传感单元的有前途的候选者。在这里，我们用带有负电荷的硼胶掺杂的HBN薄片（V $ _ {\ rm B}^ - $）中心通过中子辐照来演示定量磁成像。作为概念验证，我们为Crte $ _2 $产生的磁场图像crte $ _2 $，范德华（Van der Waals Ferromagnet）的温度略高于$ 300 $K。与其他嵌入3D材料中的量子传感器相比，基于HBN的磁性传感器的其他量子传感器在此工作中所描述的基于HBN的磁性传感器的优势是其较高的使用，更重要的效率，并且可以使其更重要，并且能够固定，并且能够固定，并且能够使用它。这样的传感单元可能会通过提供一种简单的方法来探测范德华异质结构的物理学，从而在2D材料研究中找到许多应用。
Optically-active spin defects hosted in hexagonal boron nitride (hBN) are promising candidates for the development of a two-dimensional (2D) quantum sensing unit. Here, we demonstrate quantitative magnetic imaging with hBN flakes doped with negatively-charged boron-vacancy (V$_{\rm B}^-$) centers through neutron irradiation. As a proof-of-concept, we image the magnetic field produced by CrTe$_2$, a van der Waals ferromagnet with a Curie temperature slightly above $300$ K. Compared to other quantum sensors embedded in 3D materials, the advantages of the hBN-based magnetic sensor described in this work are its ease of use, high flexibility and, more importantly, its ability to be placed in close proximity to a target sample. Such a sensing unit will likely find numerous applications in 2D materials research by offering a simple way to probe the physics of van der Waals heterostructures.
