· 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.

Export Control

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.
