This paper is a review article covering our work in recent years on PbTe and the alloy semiconductor CdxPb1-xTe. It shows how measurements of the transport and optical properties of these materials support (1) the two valence band model for PbTe in which the principal light mass band is highly non-parabolic and the secondary heavy mass band is parabolic and (2) a value for the Hall-anisotropy factor of the principal valence band, in the case of extremely high carrier density PbTe at low temperatures, of about 1/2.
