SnS₂ Crystals

SnS₂ Crystals

SnS₂ (Tin Disulfide) is a layered van der Waals semiconductor with a hexagonal 2H phase structure, exhibiting excellent optical and electronic properties. It is widely studied for its applications in optoelectronics, photodetectors, transistors, photocatalysis, and energy storage due to its moderate bandgap, high photoconductivity, and environmental stability. Our SnS₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, well-controlled stoichiometry, and good crystallinity.
