KAg2PS4
semiconductor· KAg2PS4
KAg₂PS₄ is an experimental quaternary semiconductor compound combining potassium, silver, phosphorus, and sulfur into a mixed-anion chalcogenide structure. This material belongs to the family of silver-based sulfide/phosphide semiconductors under active research for solid-state ionic and photonic applications. While not yet commercialized at scale, compounds in this class are investigated for their potential in all-solid-state batteries, photovoltaic devices, and fast-ion conductors due to silver's high ionic mobility and the tunable bandgap available through multinary semiconductor design.
