论文摘要
我们考虑了由两个平行双层石墨烯片制成的双层系统,该石材片由介电介质分开。我们计算出两层的带电杂质,计算第一层的有限温度电导率。我们研究温度,层间距离,介电常数和杂质浓度,载体浓度对电导率的影响。我们显示了位于II层中的带电杂质在确定第一层对于小层间距离的电导率方面的重要性。本文的结果使我们对第二个效果下的双层石墨烯中的远程带电杂质散射有了更多的了解。
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 effect of the second one.
