· JVASP-67812· BeGa4Se

BeGa4Se is a quaternary ceramic compound combining beryllium, gallium, and selenium—a wide-bandgap semiconductor material belonging to the II-IV-VI family of compounds. This material is primarily of research and development interest for optoelectronic and high-temperature semiconductor applications where conventional materials reach performance limits. BeGa4Se is notable for its potential in UV/visible photonic devices and radiation-hardened electronics, though it remains largely experimental compared to more established wide-bandgap semiconductors like GaN or SiC.

Regulatory Screening

Environmental

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.
