我们提出的数值和分析结果的发射极的寿命在靠近石墨烯片。具体来说，我们分析了参与衰变过程的不同物理通道的贡献。我们的研究结果表明，测量发射体的衰减速率为传感石墨烯的光电特性提供了一种有效的途径，特别是其电子能带结构中潜在带隙的存在和大小。
We present numerical and analytical results for the lifetime of emitters in close proximity to graphene sheets. Specifically, we analyze the contributions from different physical channels that participate in the decay processes. Our results demonstrate that measuring the emitters’ decay rates provides an efficient route for sensing graphene’s optoelectronic properties, notably the existence and size of a potential band gap in its electronic band structure.
