Tigh-Binding approach for disordered system

  1. Mar 25, 2010 #1
    Hello everyone,

    I am interested in Tigh-Binding calculation of energy dispersion for non-crystalline material. I am familiar with usual tight-binding approach for periodic structure, but I don’t understand how to use it in case of disordered system, For example cluster (or quantum dot) with 2-3 atoms of carbons bonded together by sp2 orbitals.

    Any idea?

    Maybe you have a look at a book on quantum chemistry. There, the tight binding approach is known as "Extended Hueckel approximation".
