semiconductor· Ga1As0.7P0.3
Ga₁As₀.₇P₀.₃ is a III-V direct-bandgap semiconductor alloy formed by substituting phosphorus into gallium arsenide, creating a ternary compound with an intermediate bandgap energy between GaAs and GaP. This material is used primarily in optoelectronic devices where visible and near-infrared light emission or detection is required, particularly in LED and laser applications operating in the yellow-orange spectral region. Engineers select this alloy when standard GaAs devices operate at wavelengths outside the desired spectrum, leveraging its tunable bandgap to match specific emission requirements while maintaining the superior carrier mobility and crystal quality characteristic of the GaAs platform.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
