semiconductor

· Se1 Pr1

Se₁Pr₁ is a rare-earth selenium compound that belongs to the family of intermetallic semiconductors combining praseodymium (a lanthanide) with selenium. This material represents an experimental or research-phase composition rather than a widely commercialized engineering material, and is of interest for understanding electronic and structural properties in rare-earth chalcogenide systems.

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.
