论文摘要
钻石中带负荷含量的氮脱牙中心的单线状态在其光学旋转控制和读数中起着关键作用。在这项工作中，通过实验测量了迄今为止，迄今未知的电离能量，发现在1.91-2.25 eV之间。这是通过分析包含旋转控制和NV电荷状态分化的光致发光测量以及基于氮胶囊的主方程的模拟来获得的。这项工作为更准确的电离能量建立了一个协议，这可能会导致改进的读出方法。
The singlet states of the negatively-charged nitrogen-vacancy centers in diamond play a key role in its optical spin control and readout. In this work, the hitherto unknown ionization energy of the singlet is measured experimentally and found to be between 1.91-2.25 eV. This is obtained by analyzing photoluminescence measurements incorporating spin control and NV charge state differentiation, along with simulations based on the nitrogen-vacancy's master equation. This work establishes a protocol for a more accurate estimate of this ionization energy, which can possibly lead to improved read-out methods.
