· Ca6 Sn4 S14

Ca₆Sn₄S₁₄ is a mixed-cation sulfide semiconductor compound containing calcium, tin, and sulfur. This material belongs to the broader family of metal sulfides and represents a research-phase compound being investigated for optoelectronic and photovoltaic applications where wide bandgap semiconductors are desired. While not yet established in high-volume industrial production, compounds in this family are of interest as potential alternatives to conventional semiconductors due to their tunable electronic properties and earth-abundant elemental constituents.
