· SnS

Tin monosulfide (SnS) is a layered IV-VI semiconductor compound with an orthorhombic crystal structure, belonging to the family of metal chalcogenides. While primarily in the research and development phase, SnS is investigated as a promising material for optoelectronic and photovoltaic applications due to its tunable bandgap, earth-abundant composition, and potential for low-cost, large-scale manufacturing compared to conventional semiconductors. Its layered structure and anisotropic properties make it attractive for emerging thin-film technologies, though industrial deployment remains limited.
