论文摘要
我们研究了麦克沃瑟模型内的开路门电压极限中短弹道石墨烯的临界电流噪声。我们发现在较大频率范围内的闪烁噪声，并讨论噪声幅度随掺杂水平的函数的温度依赖性。在电荷中立点，我们发现一个单一的温度依赖性$ t^{ - 3} $，与固定门电压下的短弹道石墨烯约瑟夫森连接期望的线性依赖性截然不同。
We investigate critical current noise in short ballistic graphene Josephson junctions in the open-circuit gate-voltage limit within the McWorther model. We find flicker noise in a wide frequency range and discuss the temperature dependence of the noise amplitude as a function of the doping level. At the charge neutrality point we find a singular temperature dependence $T^{-3}$, strikingly different from the linear dependence expected for short ballistic graphene Josephson junctions under fixed gate voltage.
