In the past years, various work has been devoted to improving the thermoelectric figure of merit zT, and remarkable advances have been achieved. In 2019, an abnormal zT value exceeding 400 in the Cu2Se system was measured experimentally by a Japanese group. In 1993, the theoretically predicted maxim...
