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...
