· Be1 Se1

Be₁Se₁ is a binary II-VI semiconductor compound composed of beryllium and selenium, representing a wide-bandgap material in the beryllium chalcogenide family. This material is primarily of research and specialized industrial interest, with applications in optoelectronics and high-energy physics where its wide bandgap and radiation hardness are advantageous; it remains less common than alternative II-VI semiconductors (such as CdSe or ZnSe) due to beryllium's toxicity and the material's challenging synthesis and processing requirements.

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.
