Abstract

Transport properties near the Dirac point in graphene are expected to be determined by quantum many-body interactions between relativistic electrons. Experiments now show that the flow of charge and heat in high-quality graphene close to charge neutrality can be described within a hydrodynamic framework, with universal intrinsic electrical conductivity that is quantized to a value close to the quantum of conductance.

近理想石墨烯中电导率的量子化极限

石墨烯中狄拉克点附近的输运性质有望由相对论电子之间的量子多体相互作用决定。实验现在表明，高质量石墨烯中电荷和热量的流动接近电荷中性，可以在流体动力学框架内描述，具有普遍的固有电导率，被量子化到接近电导率的量子值。
