摘要：In devices used for the direct conversion of heat into electricity, or vice versa,known in the art as thermoelectric power generators, thermoelectric refrigerators andthermoelectric heat pumps, the efficiency of energy conversion and/or coefficient ofperformance have been considerably lower than those of conventional reciprocating orrotary, heat engines and/or vapor-compression systems, employing certain refrigerants.The energy conversion efficiency of power generating devices, for example, aside fromthe hot and cold junction temperatures, also depends on a parameter known in the art asthe thermoelectric figure of merit Z=S2sigma/k, where S is the thermoelectric power,sigma is the electrical conductivity and k is the thermal conductivity, of the material thatconstitutes the p-type, and/or n-type, thermoelements, or branches, of the said devices.In order to achieve a considerable increase in the energy conversion efficiency, a
thermoelectric figure of merit of the order of 10-2 K-1, or more, is needed. It is reasonablyexpected that such an order of magnitude, for the figure of merit, can be realized with acomposition of matter, comprising magnesium, silicon, lead and barium, and optionallycomprising one, or more, additional doping materials.
