PbTe is recognized as one of the best intermediate-temperature thermoelectric materials; however, its commercial applications are largely restricted by the comparatively lower performance of its n-type counterpart. Here we show that Peierls-Nabarro stress is manipulated through solute-induced lattice softening, which g...

Lead sulfide (PbS) is a promising mid-temperature thermoelectric material; however, its performance is constrained by the difficulty of simultaneously optimizing electrical transport and suppressing lattice thermal conductivity. Herein, a Bi2Se3 incorporation strategy is developed to synergistically regulate carrier an...
Polycrystalline SnP3 was synthesized via a combined process of high-energy ball milling, two-step spark plasma sintering, and thermal annealing. X-ray diffraction confirms the formation of phase-pure rhombohedral SnP3, with intermediate annealing effectively eliminating secondary phases. The sintered pellets exhibit de...

Zintl phases are crucial for Te-free power generation and electrical cooling modules, which are considered next-generation thermoelectric (TE) technology. While n-type Zintl materials, such as Mg3Sb2, have achieved remarkable performance, their p-type counterparts are restricted by electron-phonon coupling. This work d...

Two-dimensional (2D) indium selenide (InSe) holds great promise for optoelectronic applications, yet its practical application remains severely limited by high contact resistance, narrow spectral absorption range, and pronounced susceptibility to environmental degradation. Here, a bismuth (Bi) doping strategy is studie...
