Chalcopyrite CuGaTe2: A High-Efficiency Bulk Thermoelectric Material

Chalcopyrite CuGaTe2: A High-Efficiency Bulk Thermoelectric Material

CuGaTe2 with a chalcopyrite structure demonstrates promising thermoelectric properties. The maximum figure of merit ZT is 1.4 at 950 K. CuGaTe2 and related chalcopyrites are a new class of high‐efficiency bulk thermoelectric material for high‐temperature applications.
