· JVASP-54886· Ca3Ga2N4

Calcium gallium nitride (Ca₃Ga₂N₄) is a wide-bandgap ceramic compound belonging to the nitride family, combining alkaline-earth and group-III elements in a ternary nitride structure. This is primarily a research and development material being investigated for next-generation optoelectronic and semiconductor applications, particularly where wide bandgap properties and thermal stability are advantageous over conventional GaN-based systems. The material's potential lies in high-temperature electronics, UV-emitting devices, and power semiconductor applications where its unique crystal structure and electronic properties may offer performance benefits in extreme environments.
