摘要： Thermoelectric eutectic and off-eutectic compositions comprising a minor phase in a thermoelectric matrix phase are provided. These compositions include eutectic and near eutectic compositions where the matrix phase is a chalcogenide (S, Se, Te) of Ge, Sn, or Pb or an appropriate alloy of these compounds and at least one of Ge, Ge1-xSix, Si, ZnTe, and Co are precipitated as the minor phase within the matrix. Methods of making and using the compositions are also provided. The thermoelectric and mechanical properties of the compositions make them well-suited for use in thermoelectric applications. Controlled doping of eutectic compositions and hypereutectic compositions can yield large power factors. By optimizing both the thermal conductivities and power factors of the present compositions, ZT values greater than 1 can be obtained at 700K.
