SnSe₂ Crystals

SnSe₂ Crystals

SnSe₂ (Tin Diselenide) is a layered van der Waals semiconductor with a hexagonal CdI₂-type 1T phase structure, exhibiting optical, electronic, and thermoelectric properties. It has been investigated for applications in optoelectronics, photodetectors, transistors, phase-change memory, and energy storage due to its moderate bandgap and photoconductivity. SnSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
