The thermoelectric power (Seebeck coefficient) S which is one of the parameters determining the figure of merit Z of thermoelectric materials is measured for polycrystalline (PbTe), -x(Bi,Te,), solid solutions as a function of temperature T (in the interval from 80 to 350 K) and composition x (in the range 0 5 x 5 0.02). The experimental results are analyzed on the basis of the two-band nonparabolic Kane model and the transport coefficient theory of A"BV' semiconductors. Some information on the phonon-drag term in this coefficient is specially extracted from the data.KOe@@AUAeHT TePMO-3.A.C. s XBJIReTCX OnHAM A 3 IIapaMeTpOB, OIIpeAeJIRIoI4AX TepMO3JICKTpAYeCKy€O 3@@eKTABHOCTb IIOJIyIIpOBOrHAKOBbIX MaTCpAaJIOB.
