Ga1Sb0.8As0.2

GaSb₀.₈As₀.₂ is a ternary III-V semiconductor alloy combining gallium antimonide (GaSb) and gallium arsenide (GaAs), engineered to tune the bandgap and lattice parameters between these two parent compounds. This material is primarily investigated in research and specialized optoelectronic applications where intermediate bandgap energies and carrier mobilities are required, particularly in infrared detectors, thermal imaging sensors, and high-efficiency multi-junction solar cells. Its value lies in enabling wavelength tunability and lattice-matching flexibility not available from binary compounds alone, though it remains less mature than GaAs or GaSb for high-volume production.
