Scattering induced current in a tight-binding band
نویسندگان
چکیده
In the single band tight-binding approximation, we consider the transport properties of an electron subject to a homogeneous static electric field. We show that repeated interactions of the electron with two-level systems in thermal equilibrium suppress the Bloch oscillations and induce a steady current, the statistical properties of which we study.

Tight- binding study of electronic band structure of anisotropic honeycomb lattice
The two-dimensional structure of graphene, consisting of an isotropic hexagonal lattice of carbon atoms, shows fascinating electronic properties, such as a gapless energy band and Dirac fermion behavior of electrons at fermi surface. Anisotropy can be induced in this structure by electrochemical pressure. In this article, by using tight-binding method, we review anisotropy effects in the elect...
متن کاملFull-Band Quantum Transport Simulation Based on Tight-Binding Green’s Function Method
Modeling and formulation of full-band quantum transport based on a nonequilibrium tight-binding Green’s function method are presented where realistic band structures, evanescent-mode matching, space charge effect, and scattering effects are taken into account. Our results show that current-voltage characteristics of a GaAs/AlAs double-barrier RTD have larger current densities than the conventio...

By employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (CNT) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. Exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. The calculations are base...

متن کاملScattering in Si-Nanowires - Where Does it Matter?
Electron transport is computed in 3nm Si nanowires subject to incoherent scattering from phonons. The electronic structure of the nanowire is represented in an atomistic sp3d5s* tight binding basis. Phonon modes are computed in an atomistic valence force field rather than a continuum deformation potential. Atomistic transport and incoherent scattering are coupled through the non-equilibrium Gre...
