Ballistic magnetotransport in graphene

  title={Ballistic magnetotransport in graphene},
  author={Ke Wang and Tigran A. Sedrakyan},
We report that a perpendicular magnetic field introduces an anomalous interaction correction, δσ, to the static conductivity of doped graphene in the ballistic regime. The correction implies that the magnetoresistance, δρxx scales inversely with temperature δρxx(T ) ∝ 1/T in a parametrically large interval. When the disorder is scalar-like, the ∝ 1/T behavior is the leading contribution in the crossover between diffusive regime exhibiting weak localization and quantum magnetooscillations. The…

Electronic properties of graphene in a strong magnetic field
We review the basic aspects of electrons in graphene (two-dimensional graphite) exposed to a strong perpendicular magnetic field. One of its most salient features is the relativistic quantum Hall
Substrate-limited electron dynamics in graphene
We study the effects of polarizable substrates such as $\mathrm{Si}{\mathrm{O}}_{2}$ and SiC on the carrier dynamics in graphene. We find that the quasiparticle spectrum acquires a finite broadening
Friedel oscillations, impurity scattering, and temperature dependence of resistivity in graphene.
Friedel oscillations in grapehene are strongly affected by the chirality of electrons in this material and the FO of the charge density around an impurity show a faster decay than in conventional 2D electron systems.
Electron transport in disordered graphene
We study the electron transport properties of a monoatomic graphite layer (graphene) with different types of disorder. We show that the transport properties of the system depend strongly on the
The electronic properties of graphene
This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons can be
Electron-Electron Interactions in Graphene: Current Status and Perspectives
We review the problem of electron-electron interactions in graphene. Starting from the screening of long range interactions in these systems, we discuss the existence of an emerging Dirac liquid of

It is found that, irrespective of the doping level, disordered graphene is subject to the common mechanisms of Anderson localization, which protects the conductivity of the system to an extend that strong localization may not be seen even at temperatures much smaller than those underlying present experimental work.
Electronic transport in two-dimensional graphene
We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier transport in doped or gated graphene
Composite fermion state of graphene as a Haldane-Chern insulator
The properties of interacting electrons in a half-filled Landau level are well addressed by the Halperin-Lee-Read (HLR) picture of non-interacting composite fermions. We discuss how such a
