TL;DR: In this article, a relatively good ZT of ∼0.6 was achieved by Te doping on the Sb site, which can be attributed to the combination of high majority-carrier concentration and enlarged band gap.

TL;DR: In this article, a detailed study on the mechanical properties of nanostructured α-MgAgSb is presented, where the Young's modulus, nanoindentation hardness, compressive strength, and fracture toughness are compared with other p-type thermoelectric materials.

TL;DR: In this article, the authors investigated the microscopic mechanism of low lattice thermal conductivity for α-MgAgSb using density functional theory (DFT) calculations and showed that a large number of optical branches, weak chemical bonding, and strong anharmonic coupling between longitudinal acoustic (LA) and longitudinal optical (LO) branches contribute to the low κlat.

TL;DR: The high thermoelectric performance of Ca-doped AgSbSe2 with a hierarchical microstructure using a facile approach, namely, mechanical alloying (for only 30 min) and a quick hot-pressing method highlights AgSBSe2-based materials as robust thermoeLECTric candidates for energy harvesting.

TL;DR: In this article, the effect of doping site on the carrier transport behavior of nanostructured α-MgAgSb was investigated, and it was demonstrated that Ca doping on the Mg site leads to higher mobility and power factor in comparison with doping on Sb site, originated from the less introduced perturbation to valence band upon doping.
