"Secondary phase effect on the thermoelectricity by doping Ag in SnSe" by Rathinam Vasudevan, Lijuan Zhang et al.
Partial replacement of Sn with Ag is an effective method to optimize the thermoelectric performance of SnSe compounds. However, this approach can easily introduce the AgSnSe2 secondary phase due to the limited solubility of Ag in SnSe. This secondary phase is considered to play positive effects on thermoelectric performance all the way in the previous studies. However, its exact influences on the sample's properties remain ambiguous. Herein, we report a comprehensive study on the crystal structures and the effects of Ag dopant in SnSe polycrystals. Firstly, neutron powder diffraction meas...
