Abstract

Grain size significantly affects the thermoelectric performance, the thickness of oxidized/amorphous layer and the stability of SnSe polycrystals. As a result, sample Sn<sub>0.97</sub>Na<sub>0.03</sub>Se with average grain size around 4 μm achieves a high thermoelectric performance and stability in the whole measured temperature range.
