Ga₁As₀.₈P₀.₂ is a III-V semiconductor alloy in the gallium arsenide phosphide family, formed by substituting 20% of arsenic with phosphorus in the GaAs lattice. This quaternary compound is primarily used in optoelectronic devices where the bandgap tuning between GaAs and GaP is needed to control emission wavelength and electrical performance; it is notably employed in red and orange light-emitting diodes (LEDs) and specialized photodetectors that require specific spectral response windows. The material offers a practical middle ground between pure GaAs (infrared-focused) and GaP (visible green/yellow) compositions, making it valuable for applications where wavelength precision and lattice compatibility matter.
