· JVASP-120197· GaPSe

GaPSe is a III-V semiconductor ceramic compound composed of gallium, phosphorus, and selenium, belonging to the family of mixed-anion semiconductors. This material is primarily of research interest for optoelectronic and photonic applications, where its wide bandgap and crystal structure offer potential advantages in ultraviolet to infrared wavelength detection and emission. Engineers consider GaPSe for specialized applications requiring tunable optical properties and high-frequency electronic performance, though it remains less commercialized than conventional GaAs or GaP semiconductors.

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.
