Sn-Doping-Induced Biphasic Structure Advances Ductile Ag₂S-Based Thermoelectrics.

ABSTRACT: Due to its inherent ductility, Ag₂S shows promise as a flexible thermoelectric material for harnessing waste heat from diverse sources. However, its thermoelectric performance remains subpar, and existing enhancement strategies often compromise its ductility. In this study, a novel Sn-doping-induced biphasic structuring approach is introduced to synergistically control electron and phonon transport. Specifically, Sn-doping is incorporated into Ag₂S_0.7Se_0.3 to form a biphasic composition comprising (Ag, Sn)₂S_0.7Se_0.3 as the primary phase and Ag₂S_0.7Se_0.3 as the secondary phase. This biphasic configuration achieves a competitive figure-of-merit ZT of 0.42 at 343 K while retaining exc
