· Ce1 S1

Ce₁S₁ is a rare-earth chalcogenide semiconductor compound combining cerium with sulfur, belonging to the family of lanthanide sulfides studied for their unique electronic and optical properties. This material is primarily explored in research contexts for optoelectronic and photonic applications where rare-earth dopants or hosts are needed, as well as potential thermoelectric and magnetic device applications. Compared to more common semiconductors, cerium sulfide offers distinctive properties from cerium's f-electron character, making it relevant where rare-earth functionality is required rather than conventional Si or GaAs-based solutions.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
