1. IntroductionAs the energy crisis emerges, waste heat recovery has become one of the effective ways to solve the problem of energy shortage [1]. Thermoelectric materials play a pivotal role in the waste-heat-collection process. Thermoelectric materials have broad application prospects in fields such as isotope batteries for aerospace, high-temperature flue-gas-waste-heat recovery power generation, high-temperature steel billet waste-heat-power generation, and geothermal power generation.
