The tight-binding approach to the problem of the electronic energy levels in solids is intuitively very appealing. The method provides a real space picture of the electronic interactions which give rise to the particular features of the energy band structure, density of states, etc. This is extremely useful in studies of how these features change when the electronic configuration is altered. Th...

Abstract The tight-binding (TB) method is an ideal candidate for determining electronic and transport properties a large-scale system. It describes the system as real-space Hamiltonian matrices expressed on manageable number of parameters, leading to substantially lower computational costs than ab-initio methods. Since whole defined by parameterization scheme, choice TB parameters decides relia...

Among graphene-like family, phosphorene is a typical semiconducting layered material, which can also be a superconductor in low temperature. Applying pressure or tension on phosphorene lattice results in changing the hopping terms, which change the energy bands of the material. In this research we use the tight-binding Hamiltonian, including relevant hopping terms, to calculate energy bands of ...
