TL;DR: enhanced thermoelectric performance in SnTe, where significantly improved electrical transport properties and reduced thermal conductivity were achieved simultaneously are reported, suggesting that SnTe is a robust candidate for medium-temperature thermoelectedric applications.

TL;DR: In this paper, the authors show that the addition of Mn (0-50%) induces multiple effects on the band structure and microstructure of SnTe, including tuning the Fermi level and promoting the convergence of the two valence bands, concurrently enhancing the Seebeck coefficient.

TL;DR: The high thermoelectric performance of p-type polycrystalline SnSe is reported by the synergistic tailoring of band structures and atomic-scale defect phonon scattering through (Na,K)-codoping, resulting in an enhancement in the Seebeck coefficient and increase in the power factor.

TL;DR: In this article, a PbTe1−xSex-2%Na-y%SrTe system is investigated and a high maximum ZT of 2.3 at 923 K for PbTE0.85Se0.15-2Na-4% SrTe is reported, achieved by performing electronic band structures modifications as well as all-scale hierarchical structuring.

TL;DR: It is reported that K2Bi8Se13 exhibits multiple conduction bands that lie close in energy and can be activated through doping, leading to a highly enhanced Seebeck coefficient and a high power factor with elevated temperature.
