Cross-Scale Defects Enable Ultralow Lattice Thermal Conductivity and High Thermoelectric Performance in Silver Nanowire-Integrated Bi2Te3/Sb2Te3 Nanoheterojunctions.
Decoupling the intrinsically coupled electrical and thermal transport remains a central challenge for achieving high-performance thermoelectrics. Herein, we report a defect-modulated transport-decoupling strategy in anisotropic Bi2Te3/Sb2Te3 (BT/ST) heterojunction nanomaterials with silver nanowires. By guiding defect...
