英文摘要 | Lead-free tin sulfide (SnS), with an analogous structure to SnSe, has attracted increasing attention because of its theoretically predicted high thermoelectric performance. In practice, however, polycrystalline SnS performs rather poorly as a result of its low power factor. In this work, bulk sodium (Na)-doped SnS single crystals are synthesized using a modified Bridgman method and a detailed transport evaluation is conducted. The highest zT value of ≈1.1 is reached at 870 K in a 2 at% Na-doped SnS single crystal along the b-axis direction, in which high power factors (2.0 mW m−1 K−2 at room temperature) are realized. These high power factors are attributed to the high mobility associated with the single crystalline nature of the samples as well as to the enhanced carrier concentration achieved through Na doping. An effective single parabolic band model coupled with first-principles calculations is used to provide theoretical insight into the electronic transport properties. This work demonstrates that SnS-based single crystals composed of earth-abundant, low-cost, and nontoxic chemical elements can exhibit high thermoelectric performance and thus hold potential for application in the area of waste heat recovery. © 2018 WILEY-VCH Verlag GmbH & Co.
