论文摘要
我们提出了一种定量理论，即由于电荷波动噪声在$ {p} $$ - $$ -$ {n} $二极管中引起的抑制光线宽，最近在Anderson等人，Science 366，1225（2019）中观察到。我们将局部电场与二极管的电压连接起来，从而可以从实验阈值电压中识别缺陷深度。此外，我们表明，对这种自旋中心的破裂性的准确描述需要完整的自旋$ -1形式主义，该形式主义产生了双指数的脱碳过程，并预测了减少的电荷波动噪声如何抑制旋转中心的腐蚀速率。
We present a quantitative theory of the suppression of the optical linewidth due to charge fluctuation noise in a ${p}$$-$${n}$ diode, recently observed in Anderson et al., Science 366, 1225 (2019). We connect the local electric field with the voltage across the diode, allowing for the identification of the defect depth from the experimental threshold voltage. Furthermore, we show that an accurate description of the decoherence of such spin centers requires a complete spin$-$1 formalism that yields a bi-exponential decoherence process, and predict how reduced charge fluctuation noise suppresses the spin center's decoherence rate.
