In0.8Ga0.2As1 is a ternary III–V semiconductor alloy combining indium, gallium, and arsenic, engineered to deliver a bandgap intermediate between InAs and GaAs. This composition is primarily of research and specialized photonic interest, used in high-speed optoelectronic devices, infrared detectors, and quantum well structures where the tuned bandgap enables detection or emission in the near- to mid-infrared spectrum. Engineers select this alloy when lattice-matching constraints and specific optical wavelength requirements cannot be met by binary III–V compounds, though it remains less common in production than its parent materials.
