Native Defects-Induced Fermi-Level Pinning and Diffuson-Mediated Thermal Transport in BiSbSe3 Thermoelectrics.
Ultralow thermal conductivity is widely recognized as a core characteristic of promising thermoelectrics, yet many such materials still fail to realize high thermoelectric performance. Te-free BiSbSe3 embodies this contradiction: its intrinsically ultralow thermal conductivity makes it promising for medium-temperature...
