Tin disulfide, SnS2

Tin disulfide (SnS2) is a layered material with a hexagonal crystal structure. It is an n-type semiconductor and exhibits a direct bandgap, making it of interest for optoelectronic applications. Due to its semiconducting nature, it has potential uses in photodetectors, solar cells, and field-effect transistors. Additionally, SnS2 has shown promise in the field of energy storage and can be employed as an anode material in lithium-ion batteries. The layered structure of SnS2 also means that it can be exfoliated into thin layers or nanosheets, similar to graphene, enabling its use in the growing field of two-dimensional materials for next-generation devices.
