Title:
熱電変換材料と電界印加型熱電変換素子
Document Type and Number:
Japanese Patent JP5723591
Kind Code:
B2
Abstract:
A thermoelectric conversion device includes a Heusler alloy film having a structure of B2 or L21 in notation of A2BC and a pair of electrodes on the Heusler alloy film to output an electromotive force generated by a thermal gradient in the Heusler alloy film. The thermoelectric conversion device further includes an electrode for applying an electric field or a voltage to the Heusler alloy film to increase and control an electric conductivity and a Seebeck coefficient S of the Heusler metal film. The device can control to increase an electric conductivity and Seebeck coefficient S by applying an electric field or a voltage through an insulation film to the Heusler alloy film. The device may have a shared connection to select one of outputs of a plurality of thermoelectric conversion devices arranged in a matrix or increase an electromotive force as an output.
