Ce2Se3

Ce2Se3 is a rare-earth selenide compound belonging to the family of lanthanide chalcogenides, composed of cerium and selenium in a 2:3 stoichiometric ratio. This material is primarily investigated in research contexts for optoelectronic and thermoelectric applications, where its narrow bandgap and rare-earth electronic structure offer potential advantages over conventional semiconductors in infrared detection, photovoltaic devices, and solid-state cooling systems. Ce2Se3 remains largely in the exploratory phase rather than established in high-volume industrial production, but the rare-earth selenide family is gaining interest as alternative semiconductor platforms where tunable electronic properties and thermal performance could provide benefits in niche applications where standard silicon or III-V compounds are insufficient.
