· Ba2 Cu1 Hg1 O4

Ba₂Cu₁Hg₁O₄ is an experimental mixed-metal oxide semiconductor containing barium, copper, and mercury in a layered perovskite-related structure. This compound belongs to the family of high-temperature superconductor precursors and exotic oxide semiconductors, primarily studied in condensed matter physics and materials chemistry research rather than established industrial applications. The material's notable feature is the incorporation of mercury—a highly toxic element—which limits practical deployment, making it primarily relevant for fundamental research into electron correlations, magnetism, and unusual transport phenomena in cuprate-based systems.
