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 ...

of such defects, their influence is still significant for many investigations. Conversely, tailoring of material properties by defect engineering7, chemical doping or functionalization inherently introduces point defects into the material8. An accurate description of how these defects modify the electronic ...
,of 摘要: In our previous paper (Phys. Rev. B 89, 165430 (2014)) we have found that in graphene, in distinction to the four occupied bands, which can be described by the simple tight-binding model (TBM) with four atomic orbitals per atom, the two lowest lying at the Γ-point ...
A wavefunction is a mathematical description of the quantum state of a particle, which includes information about its position and momentum. In the context of graphene, the wavefunction describes the behavior of electrons in the material. What is the tight binding method for expressing graphene wave...

The existing tight binding models can very well reproduce the ab initio band structure of a 2D graphene sheet. For graphene nano-ribbons (GNRs), the current sets of tight binding parameters can successfully describe the semi-conducting behavior of all armchair GNRs. However, they are still failin...
We apply this parameterization to penta-graphene nanoribbons, achieving an adequate description of quantum-size effects. Additionally, a symmetry-based analysis of the energy band structure and the optical transitions involved in the absorption spectra is introduced, allowing for the interpretation of the...
