GaPS
ceramic· JVASP-121052· GaPS
Gallium phosphide (GaP) is a III-V compound semiconductor ceramic with a direct bandgap, commonly used in optoelectronic and photonic applications where efficient light emission and detection are required. It serves as a foundation material in light-emitting diodes (LEDs), particularly in green and yellow wavelength ranges, and in photovoltaic cells for space and high-efficiency terrestrial applications. Engineers select GaP over alternative semiconductors when wavelength specificity, radiation hardness, or thermal stability in demanding environments becomes critical.

Regulatory Screening
Environmental
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.
