SnSe Crystals

SnSe Crystals

SnSe (Tin Selenide) is a layered semiconductor with an orthorhombic crystal structure and thermoelectric properties characterized by its Seebeck coefficient and low thermal conductivity. It exhibits anisotropic electronic and optical characteristics, supporting applications in thermoelectrics, optoelectronics, nanoelectronics, and 2D material research. SnSe crystals are synthesized using the Chemical Vapor Transport (CVT) method.
