TL;DR: In this article, the texture-dependent thermoelectric properties of Bi2Te3 pellets were optimized by the proper texture design to simultaneously secure a high carrier mobility and strong phonon scattering, resulting in a peak ZT value of 0.69 at 333 K.

TL;DR: An energy- and time-efficient wet mechanical alloying and spark plasma sintering method is developed to prepare porous β-Ag2Se with hierarchical structures including high- density pores, a metastable phase, nanosized grains, semi-coherent grain boundaries, high-density dislocations, and localized strains, suggesting that β- Ag2Se can be a competitive candidate for room-temperature thermoelectric applications.

TL;DR: Nanostructured monoclinic Cu2Se with a low carrier concentration has been synthesized by a wet mechanical alloying process combined with spark plasma sintering and obtains a figure of merit of 0.72 at 380 K with good thermal stability.

TL;DR: In this paper, a facile amorphous Sb2S3 induced interface engineering strategy was proposed for the development of high performance (Bi, Sb)2Te3-based thermoelectric materials.

TL;DR: In this paper, a nano-twinned CuAgSe secondary phase was introduced to achieve simultaneously increased compressive strength and plasticity of the β-Ag2Se pellets without sacrificing the thermoelectric performance.
