· Ag4 As4 Se4

Ag₄As₄Se₄ is a quaternary chalcogenide semiconductor compound combining silver, arsenic, and selenium elements in a layered crystal structure. This material belongs to the family of superionic conductors and mixed-valence semiconductors, primarily investigated in research contexts for its potential ionic and electronic transport properties. Industrial applications remain limited, though the material shows promise in solid-state ionics, photovoltaic devices, and phase-change memory technologies where its unique electronic structure and ion mobility could offer advantages over conventional semiconductors.
