· As4S4

As₄S₄ is an arsenic sulfide compound belonging to the chalcogenide semiconductor family, characterized by strong covalent bonding between arsenic and sulfur atoms. This material exists primarily in research and specialized optical applications rather than high-volume industrial production, with potential interest in infrared optics, photonic devices, and emerging areas of nonlinear optics where its bandgap and refractive properties offer advantages over more conventional semiconductors. Engineers typically evaluate As₄S₄ when designing systems requiring mid-infrared transmission or when exploring alternative semiconductor chemistries for niche photonic applications, though commercial adoption remains limited due to material handling considerations and the availability of more established alternatives.
