· Sc2S3

Scandium sulfide (Sc₂S₃) is an inorganic compound semiconductor belonging to the rare-earth chalcogenide family, characterized by ionic bonding between scandium cations and sulfide anions. This material remains primarily in the research and development phase, with potential applications in optoelectronic devices, photovoltaics, and high-temperature electronics where rare-earth semiconductors offer unique optical and thermal properties. Sc₂S₃ is of interest to researchers exploring alternatives to more common semiconductors in niche applications requiring high-temperature stability or specific optical bandgap characteristics.
