Se1 Pr1
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.
