· JVASP-17318· PaAs

Phosphorus arsenide (PaAs) is a binary semiconductor ceramic compound belonging to the III-V compound semiconductor family, characterized by its crystalline structure and electronic properties. It is primarily investigated in research contexts for optoelectronic and high-frequency electronic applications where direct bandgap semiconductors are advantageous. PaAs is notable within the arsenide family for potential use in infrared emitters, detectors, and high-speed devices, though it remains less commercially established than related compounds like GaAs; engineers would consider it when exploring emerging semiconductor materials for specialized photonic or RF applications.
