· Er1 H3

Er₁H₃ is a rare-earth hydride semiconductor compound combining erbium metal with hydrogen. This material belongs to the class of lanthanide hydrides, which are research-phase materials explored for their unique electronic and optical properties arising from the interaction between rare-earth elements and hydrogen lattices. Er₁H₃ is primarily of scientific interest rather than established industrial production, with potential applications in advanced optoelectronics and hydrogen storage research where its semiconductor characteristics and rare-earth content could enable novel device functionality.

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.
