Grain size optimization for high-performance polycrystalline SnSe thermoelectrics
Kunling Peng,Kunling Peng,Hong Wu,Hong Wu,Yanci Yan,Yanci Yan,Lijie Guo,Guoyu Wang,Xu Lu,Xiaoyuan Zhou +9 more
TL;DR: In this article, the authors investigated the thermoelectric properties of polycrystalline Sn0.97Na0.03Se polycrystals and found that the oxidization during powder processing or after SPS greatly decreases the carrier concentration, and the increased oxidized/amorphous grain boundaries reduce the carrier mobility, leading to an order of magnitude reduction in the electrical conductivity compared to that of the single crystals.
