· Ag2 I2

Silver iodide (Ag₂I₂) is an ionic semiconductor compound belonging to the family of silver halides, known for its mixed-valence silver chemistry and layered crystal structure. This material is primarily investigated in research contexts for optoelectronic applications, photographic emulsions, and solid-state ionic conductors, where its unique combination of ionic conductivity and semiconducting properties offers potential advantages over conventional single-component halides in specialized electrochemical and photonic devices.
