--- _id: '11142' abstract: - lang: eng text: SnTe is a promising Pb-free thermoelectric (TE) material with high electrical conductivity. We discovered the synergistic effect of Bi2O3 on enhancing the average power factor (PF) and overall ZT value of the SnTe-based thermoelectric material. The introduction of Bi2O3 forms plenty of SnO2, Bi2O3, and Bi-rich nanoprecipitates. These interfaces between the SnTe matrix and the nanoprecipitates can enhance the average PF through the energy filtering effect. On the other hand, abundant and diverse nanoprecipitates can significantly diminish the lattice thermal conductivity (κlat) through enhanced phonon scattering. The synergistic effect of Bi2O3 resulted in a maximum ZT (ZTmax) value of 0.9 at SnTe-2% Bi2O3 and an average ZT (ZTave) value of 0.4 for SnTe-4% Bi2O3 from 300 K to 823 K. The work provides an excellent reference to develop non-toxic high-performance TE materials. acknowledgement: This work was supported by National Natural Science Foundation of China (52002042), National Key Research and Development Program of China (2018YFA0702100 and 2018YFB0703600), 111 Project (B17002) and Lise Meitner Project M 2889-N.
