Graphene Carrier Transport Theory

摘要: This chapter describes the theory of carrier transport in two-dimensional graphene sheets. At high density, conductivity depends on dielectric constant substrate, and properties impurity potential, which all can be treated using Boltzmann formalism. low disorder causes local random fluctuations density to exceed average density. As a consequence, at Dirac point is highly inhomogeneous. The ensemble-averaged these puddles electrons holes are described by self-consistent theory, this inhomogeneous medium given an effective theory. Comparing with results representative experiments rigorously tests it validity accuracy.
