Selective Interfacial Barriers Drive High‐Performance GeTe Thermoelectrics

Advanced Science, EarlyView.
Carrier‐phonon decoupling is the key to developing high‐performance thermoelectric materials. Here, we demonstrate that selective interfacial barriers can decouple carrier and phonon transport, thus achieving an exceptional peak ZT of ∼2.7 at 773 K, along with a record‐high average ZT of 1.9 across 300–773 K in the (Ge0.82Mn0.04Bi0.04Pb0.1Te)0.99(VSe2 ...

Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Coupled Vacancy and Phonon‐Scattering Engineering Drive Defect Evolution Toward Multifunctional High‐Performance Bi2Te3 Thermoelectrics

Advanced Science, EarlyView.
ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...
