GaAs₀.₆₅Sb₀.₃₅ is a III-V compound semiconductor alloy combining gallium arsenide and gallium antimonide in a 65:35 ratio, engineered to achieve a narrow bandgap suitable for infrared applications. This material is primarily used in infrared photodetectors, thermal imaging sensors, and long-wavelength optoelectronic devices operating in the 3–5 μm atmospheric transmission window. The specific composition balances lattice matching requirements with bandgap tuning, making it a preferred choice over binary GaAs or GaSb alone for mid-infrared detection where sensitivity, spectral response, and thermal stability are critical.
