The search for alternative energy sources is presently at the forefront of applied research. In this context, thermoelectricity for direct energy conversion from thermal to electrical energy plays an important role. This?paper is concerned with the development of highly efficient p-type [(PbTe)(SnTe)(Bi 2Te 3)] x (GeTe) 1-x alloys for thermoelectric applications using spark plasma sintering (SPS). Varying the carrier concentration of GeTe was achieved by alloying of PbTe, SnTe, and/or Bi 2Te 3. The rhombohedral to cubic phase transition temperature, T c, was found to be sensitive to the degree of alloying. Highest power factor values (P = 33 μW/cm K 2) were obtained for (GeTe) 0.95(Bi 2Te 3) 0.05 composition.
