GaAs0.3P0.7
semiconductorGaAs₀.₃P₀.₇ is a III-V direct-bandgap semiconductor alloy combining gallium arsenide (GaAs) and gallium phosphide (GaP), engineered to achieve intermediate optoelectronic properties between its parent compounds. This material is primarily used in light-emitting devices and photodetectors operating in the visible to near-infrared spectrum, with historical importance in early LED technology and applications requiring efficient photon emission at wavelengths around 560–650 nm (red-orange light range). Engineers select this alloy when lattice-matching to GaAs substrates is required while tuning the bandgap for specific wavelength requirements, making it valuable in indicators, display backlighting, and integrated photonic circuits where direct-bandgap performance and monolithic integration are critical.
