AgGaS2
semiconductor· AgGaS2
AgGaS₂ is a ternary III-VI semiconductor compound combining silver, gallium, and sulfur in a chalcopyrite crystal structure. It is primarily investigated as a nonlinear optical material and infrared detector medium, particularly valued for mid-infrared to far-infrared wavelength applications where transparency and frequency-conversion efficiency exceed conventional alternatives like GaAs or ZnSe. While largely confined to research and specialized optics development rather than high-volume production, AgGaS₂ is notable for enabling parametric oscillators, laser frequency conversion, and thermal imaging systems in environments where competing materials are either optically opaque or mechanically fragile.

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.
