多层石墨烯的输运性质

Transport properties of multilayer graphene

Glenn Wagner, Dung X. Nguyen, Steven H. Simon

摘要:

我们应用半经典量子玻尔兹曼形式主义的多层石墨烯的输运性质的计算。我们计算的电导率,以及导热系数和热电势的Bernal堆叠多层膜的偶数层。我们发现,在多层石墨烯的流体动力学传输的窗口是类似的双层石墨烯的情况下。我们介绍了一个简单的流体动力学模型,我们称之为多流体模型,它可以用来重现量子玻尔兹曼方程的电导率和热电势的结果。

英文摘要:

We apply the semi-classical quantum Boltzmann formalism for the computation of transport properties to multilayer graphene. We compute the electrical conductivity as well as the thermal conductivity and thermopower for Bernal-stacked multilayers with an even number of layers. We show that the window for hydrodynamic transport in multilayer graphene is similar to the case of bilayer graphene. We introduce a simple hydrodynamic model which we dub the multi-fluid model and which can be used to reproduce the results for the electrical conductivity and thermopower from the quantum Boltzmann equation.
