GaAs0.7P0.3 is a III–V semiconductor alloy composed of gallium arsenide and gallium phosphide in a 70:30 ratio, engineered to achieve intermediate bandgap and lattice parameters between its binary endpoints. This direct-bandgap material is widely used in optoelectronic devices—particularly red and orange light-emitting diodes (LEDs), laser diodes, and photodetectors—where its tunable bandgap allows emission or detection in the visible and near-infrared spectrum. The alloy is valued for high quantum efficiency, good thermal stability, and compatibility with existing GaAs/GaP processing, making it a practical choice where specific wavelength targeting or lattice matching to substrates is required.
