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 …

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …

The dynamical dielectric function of two-dimensional graphene at arbitrary wave vector q
and frequency ω, ϵ (q, ω), is calculated in the self-consistent-field approximation. The results …

Owing to its excellent electrical, mechanical, thermal and optical properties, graphene has
attracted great interests since it was successfully exfoliated in 2004. Its two dimensional …

In this paper we propose and discuss coherent terahertz sources based on charge density
wave (plasmon) amplification in two-dimensional graphene. The coupling of the plasmons to …

The diverse applications of terahertz (THz) radiation and its importance to fundamental
science makes finding ways to generate, manipulate and detect THz radiation one of the key …

We investigate the long-wavelength dispersion of longitudinal and transverse optical
phonon modes in polar two-dimensional materials, multilayers, and their heterostructures …

We investigate the geometric, electric, and optical properties of two-dimensional honeycomb
lattices using first-principles simulations. The main focus of this work is on the similarities …

We study the effects of site dilution disorder on the electronic properties in graphene
multilayers, in particular the bilayer and the infinite stack. The simplicity of the model allows …

Collective excitations of coupled electron-phonon systems are calculated for both monolayer
and bilayer graphenes, taking into account the nonperturbative Coulomb coupling between …
