Functional secondary phases reconcile thermoelectric performance and ductility in Ag 2 S-based thermoelectrics

This is the authors' abstract. We don't add key points for this paper.

In situ Sb 2 S 3 secondary-phase engineering enables energy filtering and multiscale phonon scattering in ductile Ag 2 S 0.5 Se 0.5 , simultaneously enhancing thermoelectric performance and mechanical flexibility for wearable energy harvesting.
