Stabilized Cubic GeTe With Matched Grain-Boundary Networks and Band Convergence for High-Performance Dual-Mode Thermoelectric Devices. [PDF]
Adv Sci (Weinh)I‐doping stabilizes the cubic phase of GeTe and generates “electron‐transparent, phonon‐blocking” grain boundary networks while inducing valence‐band convergence. This synergistic structural‐electronic design enables effective electron‐phonon decoupling, achieving an exceptional average zTave of ∼1.62, a peak zT of ∼2.2, and enhanced mechanical ...
