Electronic and optical properties of pure and doped boron-nitride nanotube
Band structure of the carbon doped zigzag boron nitride nanotubes (BNNTs) is calculated by a simple
tight-binding model. It was found that the doping effect of B-substituted and N-substituted BNNT is
different and carbon substitution...
Electronic properties of α -graphyne nanoribbons under the electric field effect
In this paper, we investigate the electronic structure of both armchair and zigzag α -graphyne nanor-
ibbons. We use a simple tight binding model to study the variation of the electronic band gap in
α -graphyne nanoribbon. The effects...
Electrically Engineered Band Gap in Two-Dimensional Ge, Sn, and Pb: A First-Principles and Tight-Binding Approach
First-principles calculations were performed to investigate the electronic structure of two-dimensional (2-D) Ge, Sn, and Pb without and with the presence of an external electric field in combination with spin–orbit coupling. Tight-binding...
Transport properties of an armchair boron-nitride nanoribbon embedded between two graphene electrodes
Transport properties of an armchair boron-nitride nanoribbon (ABNNR) between two armchair
graphene nanoribbons (AGNRs) have been studied using the tight binding approach in the nearest
neighbor approximation. The tight biding...
Possible polaron formation of zigzag graphene nano-ribbon in the
In this article we study the role of Rashba spin–orbit coupling and electron–phonon interaction on the
electronic structure of zigzag graphene nanoribbon with different width. The total Hamiltonian of nanoribbon is written in the tight...
An Analytical Fifth-Nearest Neighbor Tight-Binding Investigation of the Effect of Mechanical Deformations on SWCNTs
(SWCNTs) using the nearest neighbor, the third-nearest neighbor (3-NN-TB) and the fifth-nearest neighbor tight-binding (5-NN-TB) approaches to compare the estimated band gap and the density of states of the three methods. To do this, we not only make use...
Estimation of the Young’s modulus of single-walled carbon nanotubes under electric field using tight-binding method
In this paper, the Young’s modulus of single-walled carbon nanotubes
(SWCNTs) under uniaxial strain is studied by using the
tight-binding method in the nearest neighbor approximation while
the curvature effect take into account...
