Gallium phosphide (GaP) is a III-V compound semiconductor formed from gallium and phosphorus, characterized by a direct bandgap structure that makes it useful for optoelectronic applications. Historically significant in LED technology—particularly for red and yellow LEDs—GaP has been a workhorse material in indicator lights, display applications, and early-generation photonic devices. While newer materials like GaN now dominate high-brightness LED markets, GaP remains relevant in niche optoelectronic applications where its proven performance, cost-effectiveness, and established manufacturing processes provide engineering value.
