· Cs2Sn3(SbS5)2

Cs2Sn3(SbS5)2 is a ternary chalcogenide semiconductor composed of cesium, tin, and antimony sulfide units, representing an emerging compound in the family of metal sulfide semiconductors. This material is primarily of research interest for optoelectronic and solid-state device applications, where its narrow bandgap and sulfide-based chemistry position it as a candidate for infrared detection, photovoltaic, or thermoelectric energy conversion. While not yet established in high-volume industrial production, compounds in this chalcogenide family are being investigated as alternatives to conventional semiconductors in niche applications requiring thermal stability or specific spectral response ranges.
