Ba4 Na1 Au1 O8

Ba₄Na₁Au₁O₈ is an experimental mixed-metal oxide semiconductor containing barium, sodium, and gold in an ordered crystalline structure. This compound belongs to the family of complex oxide semiconductors being investigated for novel electronic and photonic applications where the combination of alkali, alkaline-earth, and precious metals creates unique electronic properties unavailable in simpler binary or ternary oxides. While not yet commercially established, materials in this compositional space are of research interest for potential applications in optoelectronics, catalysis, and solid-state devices where the gold coordination and ionic flexibility of the barium-sodium framework may enable tunable band structures.
