摘要： A composite material (70) with tailored anisotropic electrical and thermal conductivities is described. A material consists of a matrix material (50, 56, 62) containing inclusions (52, 58) with anisotropic geometrical shapes. The inclusions are arranged in layers oriented perpendicular to the principal direction of electrical and thermal energy flow in the material. The shapes of the inclusions are such that they represent strong or weak barriers to energy flow depending on whether the major axis of the inclusions are parallel to or antiparallel to the flow direction.

摘要： A p or n type thermoelectric material containing, as constituent elements, at least one of Bi and Sb and at least one of Te and Se. The n type one may further contain at least one element selected from I, Cl, Hg, Br, Ag, and Cu. The thermoelectric material has a sea-island microstructure, in which the sea phase is crystal grains having an average grain size of 5 µm or smaller with their c-axes aligned unidirectionally, and the island phase is elongated crystal gains with an average length of 20 to 50 µm that are randomly distributed in the sea phase. The island phase has a microstructure in which at least one of the constituent elements is segregated. A process of producing the thermoelectric material includes mixing a sinter material with a powder having a higher Te content than the sinter material and applying heat and pressure to the mixture.

摘要： A thermoelectric material having enhanced Seebeck coefficient is characterized by a microstructure comprising nanoscale Pb inclusions dispersed in matrix substantially composed of PbTe. The excess Pb is obtained either by adding Pb in an amount greater than the stoichiometric amount needed to form PbTe, or by adding an additive effective to getter Te so as to produce the desired excess. The method is generally applicable to enhance thermoelectric properties of compounds of Pb, Sn or Ge, and Te, Se, or S.
