Tight-binding Central Interaction Model for the Band Structure of Silicon

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...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Comparative Analysis of Pseudo-Potential and Tight-Binding Band Structure Calculations with an Analytical Two-Band k·p Model: Conduction Band of Silicon

The k·p theory allows to describe the band structure analytically. After the pioneering work by Luttinger and Kohn [1] the six-band k·p method has become widely used to model the valence band in silicon. The conduction band in silicon is usually approximated by three pairs of equivalent minima located near the Xpoints of the Brillouin zone. It is commonly assumed that close to the minima the el...
