· Au2 S2

Au₂S₂ is an intermetallic semiconductor compound combining gold and sulfur, representing a member of the gold chalcogenide family of materials. This compound is primarily of research and developmental interest rather than established in high-volume manufacturing, with investigation focused on electronic and optoelectronic applications where the combination of noble metal and chalcogen properties could offer unique band structure characteristics. Potential advantages over conventional semiconductors include tunable electronic properties through the gold-sulfur interaction and possible applications in niche optoelectronic or sensing domains where gold-based compounds provide chemical stability or enhanced light-matter coupling.

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.
