We present an ab-initio supercell calculation of electronic band structures of (Tl delta Pb1-delta)Te with delta = 0 and 0.125. PbTe is to be a very small gap semiconductor, and Tl doping induces a quasi-impurity band in this in-gap state. A local relaxation based on ionic model is discussed. (c) 2006 Elsevier B.V.
