TL;DR: The average value of the figure of merit ZT, of more than 1.17, is measured from 300 K to 800 K along the crystallographic b-axis of 3 at% Na-doped SnSe, with the maximum ZT reaching a value of 2 at 800 K as mentioned in this paper.

TL;DR: The thermoelectric properties of solid solution CoSbS1-xSex with stiff bond and smaller Gruneisen parameters are synthesized and measured and can be extended to other high-efficiency thermoelectedric materials with stiff bonded materials.

TL;DR: In this article, a quaternary chalcogenide with ex-situ homogeneous nanoinclusions has been synthesized by ball milling, followed by spark plasma sintering.

TL;DR: In this paper, the influence of Ge substitution on the electrical transport properties of Nd-filled p-type skutterudites was investigated, and the results indicated that the large enhancement of ZT through Ge doping indicates that these compounds may have great potential for application as p type segments of thermoelectric devices.

TL;DR: In this paper, the thermoelectric properties for polycrystalline In4−x fixme Ce and Pb co-doping at the In sites were investigated and it was shown that the reduced thermal conductivity along with the boosted power factor give rise to an improvement of the dimensionless figure-of-merit, ZT, of over 65% in In4 −xcffff Ce ≥ 0.
