The thermoelectric conversion material the electronic equipment and the cooling system which have the thermoelectric sensing element and this element which use this

摘要

As it possesses the quality where electric electrical resistivity becomes low the semiconductor temperature dependancy, namely, attendant upon the rise of temperature, the thermoelectric conversion material which possesses the thermoelectric efficiency which is higher than past is offered. Formula (Bi₂ A₂ O₄) _0.5 (it makes the thermoelectric conversion material which includes the substance which possesses the stratified bronze structure which with Co_{1-xRh x}) O₂ is shown. Here, A is the alkaline earths metal element, x is the numerical value of the 0.8 or less of 0.4 or more. The thermoelectric conversion material of this invention shows satisfactory thermoelectric quality in the wide temperature limits.
