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 quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge (surface) states in graphene depend on the edge termination (zigzag or armchair) and affect the physical properties of nanoribbons. Different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of electron-electron and electron-phonon interactions in single layer and multilayer graphene are also presented.read more

Band structure and infrared absorption of graphite
W.S. Boyle,P. Nozieres +1 more
Abstract: The infrared optical properties of graphite single crystals have been calculated from a model of the band structure developed by group theory. These calculations have been compared with measurements of the emissivity and reflection coefficient of single crystals. At short wavelengths interband effects predominate: from the experimental results the maximum splitting of the pi bands at a corner of the zone has been set at 0.56 electron volt. At longer wavelengths the intraband contributions become large, giving rise to plasma effects in the neighborhood of 25 microns. This gives an approximate value of the band overlap lying between 0.04 and 0.01 electron volt. (auih)
