Mechanically Robust Dicing‐Free Thermoelectric Module Fabrication Using Anion‐Cation co‐Doped Bismuth Tellurides

Small, EarlyView.
NaCl co‐doping effectively enhances the thermoelectric performance of p‐type Bi–Sb–Te (BST) alloys through simultaneous Na+ substitution at Sb sites and Cl− substitution at Te sites, inducing local lattice distortion and defect engineering. At low doping levels, carrier transport is optimized by tuning carrier concentration and suppressing antisite ...
