High-performance low-cost thermoelectrics

Researchers have reported the high-performance SnS thermoelectric crystals combining the desirable features of low-cost, earth-abundant materials and environmental friendliness. For the first time, they discovered the interplay of triple electronic bands leading to the high performance of thermoelectric SnS crystals, which is promoted by Se alloying. Furthermore, Se alloying plays a second important role in lowering the thermal transport.
