Ga1As0.1P0.9

Ga₁As₀.₁P₀.₉ is a III-V semiconductor alloy composed of gallium, arsenic, and phosphorus, where phosphorus dominates the anion sublattice. This material belongs to the GaAsₓP₁₋ₓ family and represents a phosphorus-rich composition tuned for specific bandgap and lattice properties intermediate between GaP and GaAs. The alloy is primarily used in optoelectronic devices requiring controlled bandgap engineering, particularly in light-emitting applications and photodetectors operating in the visible to near-infrared spectrum. Engineers select this composition when lattice matching to GaP substrates or when the specific bandgap energy of the phosphorus-rich region is needed to optimize wavelength output or detection sensitivity relative to pure GaAs or GaP alternatives.
