PB-GE-TE-COMPOUNDS FOR THERMOELECTRIC GENERATORS OR PELTIER ARRANGEMENTS

摘要

A thermoelectrically active p- or n-conductive semiconductor material is constituted by a ternary compound of the general formula (I): (Pb1-xGex)Te with x value from 0.16 to 0.5, wherein 0 to 10% by weight of the ternary compound may be replaced by other metals or metal compounds, wherein the semiconductor material has a Seebeck coefficient of at least ±200 µV/K at a temperature of 25 °C.
