· K2 Na4 Au2 O4

K₂Na₄Au₂O₄ is an experimental mixed-metal oxide semiconductor containing gold, alkali metals (potassium and sodium), and oxygen. This compound belongs to the family of ternary and quaternary metal oxides under active research for novel electronic and photonic applications. As a research-phase material rather than a production commodity, it is of primary interest to materials scientists exploring unconventional semiconductor compositions, particularly those investigating how alkali metal doping and gold incorporation affect band structure, conductivity, and optical properties in oxide systems.
