An intuitive approach to some electronic properties of graphene and graphene nanoribbons is derived, by means of a Tight Binding description. Within the same model, key concepts of coherent electronic transport are reviewed. This chapter, in combination with Appendix A, build the framework with ...

We model bent graphene as a large-radius (>1 nm) single-walled carbon nanotube in order to uncover the origin of its bending rigidity. An analytic formula based on the Hückel molecular orbital theory connects the finite resistance to bending directly to the curvature-induced torsional misalignment...

The tight-binding model is used to inquire the uniaxial strain effect on the electronic structure of 2D graphene sheet and quasi-1D armchair graphene nanoribbons. The dependence of Dirac points and gap on the uniaxial strain is investigated. The band edg
