We studied theoretically the electronic transport of metallic graphene nanoribbons (GNRs) with two vacancies using the tight-binding model and Green's function method. The results show that the conductance of zigzag GNR (ZGNR) varies with the relative position of two vacancies. However, when two vac

β¦ Synopsis
A brief review is given on electronic and transport properties of monolayer graphene from a theoretical point of view. The topics include the effective-mass description of electronic states, topological anomaly associated with Berry's phase, singular diamagnetic susceptibility, zero-mode anomalies and their removal due to level broadening effects, screening effect and charged impurity scattering, the symmetry crossover among symplectic, unitary, and orthogonal due to the presence of special time reversal symmetry, and anomaly and magnetic oscillation of long-wavelength optical phonons.

We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-binding model and calculate the density of states and the conductance within the Green's function formalism based on rea
Anomalies present at zero energy are shown to give rise to a peculiar and singular behavior of the dynamical and static conductivity in two-dimensional (2D) lattices having the structure of 2D graphite.
