Tunable quantum gaps to decouple carrier and phonon transport leading to high-performance thermoelectrics

Nature Communications, 2022
Defects are believed to always scatter carriers. Here, the authors find that the quantum gaps in GeTe-based materials do not scatter carriers, which decouple the carriers and phonons transport leading to high thermoelectric performance.
