Nature of problem: The tight-binding method is a useful method for determining the electronic structure in molecules and condensed matter systems. The MathemaTB package provides an implementation of the tight-binding machinery that allows such calculations to be performed in Mathematica. There are basically three steps to make a simple tight binding code. 1) Figure out the unit cell (in your case, periodic to one direction) 2) Figure out all the atom sites, and their type (Ga, As) within that unit cell 3) Calculate the Hamiltonian matrix elements between all the basis functions at all sites (and be smart about it). The NRL Tight-Binding Fitting Code. The fitting code is not easy to be used by non-specialists. It is designed for the creation of our parameter library to be used by the Static code and the MD code. The only posible use of this code for a non-expert is when there is a need for generating a set of tight-binding parameters which have a shorter range.
