· Se1 Y1

Se1Y1 is a compound semiconductor composed of selenium and yttrium in a 1:1 stoichiometric ratio. This material belongs to the family of rare-earth selenides, which are primarily of research and developmental interest for optoelectronic and quantum applications rather than established commercial products. Yttrium selenide compounds are investigated for potential use in infrared optics, thermoelectric devices, and advanced semiconductor research, where the combination of rare-earth and chalcogenide properties may offer unique electronic or photonic characteristics not readily available in conventional semiconductors.

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.
