Abstract In this work, a vertical vapor deposition method was developed to grow SnSe single crystals. More than thirty single crystal particles were simultaneously obtained and the largest size could up to 15 × 15 × 10 mm3. The as-grown crystal is tested has nearly Sn: Se = 1: 1 stoichiometric ratio and demonstrates standard orthorhombic Pnma space group at room temperature. Electrical transport measurement shows the present SnSe single crystal has a largest electrical conductivity σ = 39.6 S cm...

Abstract SnSe crystal is an attractive Ⅳ-Ⅵ thermoelectric (TE) material. In this work, a O25 × 50 mm3 SnSe crystal was prepared using a directional solidification method. The as-grown crystal has standard Pnma structure at room temperature. The band gap Eg is determined to be 0.96 eV which agrees well with the theoretical value. Thermal expansion measurements show that SnSe crystal has significant anisotropic expansion behaviors. The linear thermal expansion along and directions are positive but...
