Thermoelectric (TE) film has wide potential application in low‐grade waste heat recovery and TE generation due to its quick response and multifunctional integration. Multi‐nanocomposite is a promising method to solve the difficulty of maintaining temperature difference and achieving a high figure of merit ZT. However, the depletion layer induced by the multi‐nanocomposite typically degrades performance...
GeTe alloy is a promising medium‐temperature thermoelectric material but with highly intrinsic hole carrier concentration by thermodynamics, making this system to be intrinsically off‐stoichiometric with Ge vacancies and Ge precipitations. Generally, an intentional increase of formation energy of Ge vacancy by element substitution will lead to an effective dissolution of Ge precipitates for reduction...
Thermoelectrics (TE), the direct solid‐state conversion of waste heat to electricity, is a promising field with potential wide‐scale application for power generation. Intrinsic conflicts in the requirements for high electrical conductivity but (a) low thermal conductivity and (b) a large Seebeck coefficient have made enhancing TE performance difficult. Several recent striking advances in the field...
