SnS₂ Crystals

SnS₂ Crystals

SnS₂ (Tin Disulfide) is a layered van der Waals semiconductor with a hexagonal 2H phase structure, exhibiting optical and electronic properties. It is investigated for applications in optoelectronics, photodetectors, transistors, photocatalysis, and energy storage due to its moderate bandgap and photoconductivity. SnS₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
