FABRICATION OF HIGH-TEMPERATURE THERMOELECTRIC COUPLE

摘要

The present invention relates to a high-temperature thermoelectric couple and the method for making the same. The method requires a very small number of fabrication steps. It includes an act of fabricating an n-type leg that, in a stacked configuration, includes a low electrical contact resistance metallization foil that is connected to each of the two sides of Lanthanum Telluride via a thin metallic adhesion layer. Additionally, a p-type leg is fabricated that, in a stacked configuration, includes a low electrical contact resistance metallization foil that is connected to each of the two sides of 14-1-11 Zintl. Finally, CTE- matched, low electrical and thermal resistance plate interconnects are used for each of the two legs to interface with the heat source and heat sink and form an electrical connection.
