We consider a double-layer system made of two parallel bilayer graphene sheets separated by a dielectric medium. We calculate the finite-temperature electrical conductivity of the first layer due to charged impurities located in two layers. We study the effects of temperature, interlayer distance, dielectric constants and impurity concentration, carrier concentration on the electrical conductivity. We show the importance of charged impurities located in layer II in determining electrical conductivity of the first layer for small interlayer distance. The results in this paper give us more understanding about the long-range charged impurity scattering in bilayer graphene under the effect of the second one.

双层-石墨烯双层中的带电杂质散射

我们考虑由两个平行的双层石墨烯片组成的双层系统，由电介质隔开。由于位于两层中的带电杂质，我们计算了第一层的有限温度电导率。我们研究了温度、层间距离、介电常数和杂质浓度、载流子浓度对电导率的影响。我们展示了位于第 II 层中的带电杂质在确定小层间距离的第一层的电导率中的重要性。本文的结果让我们对第二种效应下双层石墨烯中的长程带电杂质散射有了更多的了解。
