Description

SnSe Crystals (Tin Selenide)

SnSe (Tin Selenide) is a layered semiconductor with an orthorhombic crystal structure, known for its outstanding thermoelectric properties, high Seebeck coefficient, and low thermal conductivity. It exhibits strong anisotropic electronic and optical characteristics, making it highly suitable for applications in thermoelectrics, optoelectronics, nanoelectronics, and 2D material research. Our SnSe crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and uniform structural properties.
