· K12 As4 S16

K12As4S16 is a quaternary semiconductor compound belonging to the arsenic sulfide family, likely investigated for optoelectronic and photonic applications due to its mixed-valence composition. This material is primarily of research interest in solid-state physics and materials chemistry rather than established industrial production; it represents exploration into chalcogenide semiconductor systems where arsenic and sulfur combinations can produce tunable band gaps and nonlinear optical properties.
