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 controlled by application of external electric and magnetic fields, or by altering sample geometry and/or topology. The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer qu...
متن کاملElectronic properties of graphene multilayers.
We study the effects of disorder in the electronic properties of graphene multilayers, with special focus on the bilayer and the infinite stack. At low energies and long wavelengths, the electronic self-energies and density of states exhibit behavior with divergences near half filling. As a consequence, the spectral functions and the conductivities acquire anomalous properties. In particular, w...
متن کاملElectronic Properties of Multilayer Graphene
Abstract. In this chapter, we study the electronic structure of arbitrarily stacked multilayer graphene in the absence or presence of magnetic field. The energy band structure and the Landau level spectrum are obtained using a π-orbital continuum model with nearest-neighbor intralayer and interlayer tunneling terms. Using degenerate state perturbation theory, we analyze the low-energy effective...
متن کاملGate tuneable beamsplitter in ballistic graphene
We present a beam splitter in a suspended, ballistic, multiterminal, bilayer graphene device. By using local bottomgates, a p-n interface tilted with respect to the current direction can be formed. We show that the p-n interface acts as a semi-transparent mirror in the bipolar regime and that the reflectance and transmittance of the p-n interface can be tuned by the gate voltages. Moreover, by ...
متن کاملThe elementary electronic properties of graphene
Quantum electrodynamics (QED) has made a clear understanding of phenomena from particle physics to astrophysics (high energy). But these phenomena have never observed in condensed matter system (low energy), until the discovery of graphene six years ago [1, 2]. The electron transport in graphene is essentially described by Dirac’s relativistic equation, not the non-relativistic Schrödinger equa...
