Ga₀.₈Al₀.₂P is a direct-bandgap III-V semiconductor alloy composed of gallium phosphide and aluminum phosphide, positioned between pure GaP and AlP in the compositional phase space. This material is used primarily in optoelectronic devices, particularly red and amber light-emitting diodes (LEDs) and infrared detectors, where its bandgap energy and direct transition characteristics enable efficient photon emission. The aluminum content raises the bandgap relative to pure GaP, shifting emission toward shorter wavelengths and improving lattice matching with certain substrates; this composition exemplifies the tunable bandgap strategy central to III-V semiconductor engineering.
