Ga1.01Sb0.99Se0.03

Ga₁.₀₁Sb₀.₉₉Se₀.₀₃ is a III-V compound semiconductor alloy based on gallium antimonide with selenium doping, engineered to modify bandgap and electronic properties for infrared and optoelectronic applications. This is a research-phase material composition, part of the GaSb family which is valued for mid-to-long-wavelength infrared detection and emission where materials like InSb and HgCdTe are used; the selenium incorporation fine-tunes performance for specific wavelength windows and carrier transport characteristics. Engineers would consider this alloy where customized bandgap control, thermal stability, or detector sensitivity in the infrared spectrum is critical, though it remains primarily in development rather than high-volume production.
