Praseodymium arsenide (PrAs) is a rare-earth pnictide semiconductor compound combining praseodymium with arsenic, belonging to the family of binary intermetallic semiconductors studied primarily in condensed matter physics and materials research. While not widely deployed in commercial applications, PrAs and related rare-earth pnictides are investigated for potential use in high-frequency optoelectronics, thermoelectric devices, and quantum materials research due to their unique electronic band structures and strong spin-orbit coupling effects. The material remains largely experimental, with engineering interest concentrated in specialized research environments and emerging technologies where rare-earth compounds offer performance advantages over conventional semiconductors.
