RESUMO

We present here the band structure and the density of states of the lead salts PbTe, PbS and PbSe, resulting from the parametrized Linear Combination of Atomic Orbitals method of Slater and Koster, with the Vogl base Sp3S.; by considering first neighbors and the Pauli s relativistic hamiltonian. Our results show that with this simple model, a 20 x 20 matrix and thirteen adjustable parameters, we can acceptly reproduce the valence and the first conduction bands ca1culated by relativistic local Empirical Pseudopotential Method
