Efficient power generation near room temperature in earth-abundant thermoelectric tin sulfide via lattice ordering

The inefficient carrier transport of earth-abundant tin sulfide (SnS), arising from its intrinsically low crystal symmetry, limits its thermoelectric performance at low temperatures. Here, the substitutional Ag+ doping modifies the Na-doped SnS crystal structure by reinforcing la...

Observation of Magnetic‐Anisotropy Crossover and High‐Temperature Skyrmions in the Dirac Magnet Fe 3 Ge with a Distorted Kagome Lattice

ABSTRACT Topological materials that simultaneously host robust high‐temperature skyrmions and nontrivial electronic band structures have attracted tremendous interest owing to their distinctive advantages for both fundamental research and prospective technological applications. H...
