· Na1 Y1 Se2

Na₁Y₁Se₂ is a ternary semiconductor compound combining sodium, yttrium, and selenium in a layered crystal structure. This is a research-phase material studied primarily in materials science and solid-state chemistry contexts rather than an established industrial semiconductor; compounds in the rare-earth selenide family are investigated for potential applications in optoelectronics, photovoltaics, and thermal management due to their tunable electronic properties and crystal anisotropy.

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.
