硒化锡，是一种无机化合物，化学式为SnSe，为灰色正交晶系晶体，具半导体性。 2017年10月27日，世界卫生组织国际癌症研究机构公布的致癌物清单初步整理参考，硒和硒化合物在3类致癌物清单中。

SnSe has exhibited the highest thermoelectric material efficiency, measured by the unitless ZT parameter, of any known material (~2.62 at 923 K along the b axis and ~2.3 along the c axis). When coupled with the Carnot efficiency for heat conversion, the overall energy conversion efficiency of approximately 25%.

2018年1月8日 · It is necessary to find materials with inherent good TE properties because traditional methods to improve TE properties are too complex and costly. SnSe is a material with intrinsic ultralow lattice thermal conductivity. The highest ZT values of 2.6 along the b-axis and 2.3 along the c-axis have been observed at 923 K.

2024年10月29日 · 硒化锡（SnSe）是其中的典型代表。经过10余年的持续努力，SnSe的宽温域热电性能得到稳步提升，基于SnSe的热电器件在温差发电和电子制冷两方面皆展现出优异的转换效率。

硒化亚锡，又称一硒化锡，是一种无机化合物，化学式为SnSe。 它是窄带隙(IV-VI) 半导体 ，人们对其在低成本 光伏器件 和存储器开关器件的应用有着相当大的兴趣。

2014年4月16日 · The layered structure of SnSe derives from a distorted rock-salt structure, and features anomalously high Grüneisen parameters, which reflect the anharmonic and anisotropic bonding.

SnSe crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two SnSe sheets oriented in the (0, 0, 1) direction. Sn2+ is bonded in a 5-coordinate geometry to three equivalent Se2- atoms. There are one shorter (2.78 Å) and two longer (2.84 Å) Sn–Se bond lengths.
