--- _id: '11144' abstract: - lang: eng text: Thermoelectric materials allow for direct conversion between heat and electricity, offering the potential for power generation. The average dimensionless figure of merit ZTave determines device efficiency. N-type tin selenide crystals exhibit outstanding three-dimensional charge and two-dimensional phonon transport along the out-of-plane direction, contributing to a high maximum figure of merit Zmax of ~3.6 × 10−3 per kelvin but a moderate ZTave of ~1.1. We found an attractive high Zmax of ~4.1 × 10−3 per kelvin at 748 kelvin and a ZTave of ~1.7 at 300 to 773 kelvin in chlorine-doped and lead-alloyed tin selenide crystals by phonon-electron decoupling. The chlorine-induced low deformation potential improved the carrier mobility. The lead-induced mass and strain fluctuations reduced the lattice thermal conductivity. Phonon-electron decoupling plays a critical role to achieve high-performance thermoelectrics. acknowledgement: This work was supported by the Basic Science Center Project of the National Natural Science Foundation of China (51788104), the National Key Research and Development Program of China (2018YFA0702100), the National Science Fund for Distinguished Young Scholars (51925101), the 111 Project (B17002), the Lise Meitner Project (M2889-N), and the National Key Research and Development Program of China (2018YFB0703600).
