In the framework of the envelope function approximation a simplified effective Hamiltonian for each valley in the PbTe–Pb 1− x Sn x Te superlattice is obtained. Analytical expressions are given for the dispersion relations connected with different valleys as a function of the k x , k y transverse wave vector components.
