Weakening Local Chemical Bonds for Enhanced Thermoelectric Performance in YbMg 2 Sb 2 Zintl Compounds

ABSTRACT Alloying is a well‐established strategy for reducing lattice thermal conductivity ( κ L ) and enhancing thermoelectric performance of materials, typically explained by the Klemens model, which describes the point‐defect phonon scattering via mass and size contrasts. Yet,...
