· GaAgGeS4

GaAgGeS₄ is a quaternary semiconductor compound combining gallium, silver, germanium, and sulfur into a chalcogenide crystal structure. This is a research-phase material rather than an established commercial compound, investigated primarily for its potential in infrared optics and photonic applications due to the wide bandgap and transmission properties characteristic of sulfide-based semiconductors. The silver content and mixed-group composition make it of particular interest for nonlinear optical devices and infrared sensing applications where conventional materials have limitations.

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.
