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.

Enhanced thermoelectric properties of AgSbTe2 obtained by controlling heterophases with Ce doping

Scientific Reports, 2017
We report the enhanced thermoelectric properties of Ce-doped AgSbTe2 (AgSb1−xCexTe2) compounds. As the Ce contents increased, the proportion of heterophase Ag2Te in the AgSbTe2 gradually decreased, along with the size of the crystals.
