Scattering mechanisms and transport properties

Abstract

The chapter presents a theory of electron transport in graphene and discussion of the corresponding experimental data. We start with the discussion of quantum and classical Boltzmann equations and Kubo–Nakano–Moti formula for the electric resistivity. Further, we discuss the main extrinsic scattering mechanicsms relevant for the transport (charge impurities, resonant impurities, static ripples), and intrinsic mobility. For the latter, the role of two-phonon processes invloving flexural phonons is especially emphasized. We also consider edge scattering in graphene nanoribbons. Further, we discuss nonlocal electron transport, weak localization effects, and hydrodynamics of electron liquid in graphene.
