Ca3 Au1 N1

Ca₃Au₁N₁ is an experimental ternary nitride semiconductor compound combining calcium, gold, and nitrogen in a fixed stoichiometric ratio. This material belongs to the emerging class of metal nitride semiconductors and represents a research-phase compound rather than an established industrial material; its potential lies in exploring novel electronic, optoelectronic, or photocatalytic properties that might arise from the unique combination of an alkali-earth metal (Ca), a noble metal (Au), and nitrogen. Engineering interest in such compounds typically stems from band gap engineering, plasmonic effects from gold, and nitrogen's role in modifying electronic structure—though practical applications remain largely unexplored and would require further characterization of thermal stability, processability, and device performance.
