Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics
Advanced Functional Materials, EarlyView.The supercompliant lattice design enables the first realization of n‐type electrical transport in AgSbTe2 by overcoming intrinsic electron‐killer defects and exceeding the doping limits imposed by the conventional Hume–Rothery rule. Accordingly, the best performance n‐type Ag0.8Na0.3Sb0.6Bi0.4Te2 sample achieves a low κ of 0.27 W·m−1·K−1 that ...

Advanced Functional Materials, EarlyView.This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.
