Ce2 H2 Se2

Ce₂H₂Se₂ is a rare-earth hydride selenide compound belonging to the family of lanthanide chalcogenides, representing an emerging class of materials under active research rather than established commercial production. This material combines cerium, hydrogen, and selenium in a layered or mixed-valent structure, positioning it within the broader semiconductor family where cerium compounds are studied for their unique electronic and optical properties derived from f-electron interactions. Industrial applications remain primarily in the research domain, with potential relevance to advanced optoelectronics, solid-state hydrogen storage studies, and next-generation thermoelectric devices where rare-earth hydride selenides may offer advantages in tuning bandgap or phonon scattering behavior compared to conventional semiconductors.
