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.
