Abstract
In this chapter we examine (using the techniques developed in Chap.4) a model hamiltonian describing the problem of a substitutional impurity in a perfect periodic lattice. The hamiltonian is given by H = H 0 + H 1 where H 0 is a periodic TBH of the type studied in Chap.5 and H 1 describes the change of the potential as a result of the impurity and is given by
