石墨烯中的无序和电子输运

Disorder and Electronic Transport in Graphene

Eduardo R. Mucciolo, Caio H. Lewenkopf

摘要:

在这篇综述中,我们提供了一个帐户的最新进展,了解无序石墨烯系统中的电子输运。从理论上的描述,强调所发挥的作用,由能带结构属性和晶格对称性,我们描述了这些系统中的无序的性质及其与传输特性的关系。虽然重点主要是在理论和概念方面,连接到实验也包括在内。问题,如短期与长期的障碍,本地化(强和弱),载流子密度依赖的电导率,电导波动被认为是一些开放的问题,指出。

英文摘要:

In this review, we provide an account of the recent progress in understanding electronic transport in disordered graphene systems. Starting from a theoretical description that emphasizes the role played by band structure properties and lattice symmetries, we describe the nature of disorder in these systems and its relation to transport properties. While the focus is primarily on theoretical and conceptual aspects, connections to experiments are also included. Issues such as short versus long-range disorder, localization (strong and weak), the carrier density dependence of the conductivity, and conductance fluctuations are considered and some open problems are pointed out.
