TL;DR: In this article, a review of thermoelectric properties, applications and parameter relationships is presented, including modifications of electronic band structures and band convergence to enhance Seebeck coefficients; nanostructuring and all-scale hierarchical architecturing to reduce the lattice thermal conductivity.

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: In this paper, the authors reported that both the power factor and thermal conductivity of SnTe can be simultaneously improved through introducing its analogues (PbTe, PbSe, pbS, SnSe, and SnS) into the SnTe matrix.

TL;DR: In this paper, a high ZT value of ∼1.2 at 773 K was achieved in n-type polycrystalline SnSe, which derives from the low thermal conductivity of SnSe and enhanced electrical conductivity induced by Br doping and Pb alloying.
