Nb4 Br12 O4
semiconductor· Nb4 Br12 O4
Nb₄Br₁₂O₄ is a mixed-valence niobium bromide oxide compound belonging to the family of layered halide-based semiconductors. This is primarily a research material studied for its electronic and optical properties rather than a mature commercial compound; niobium halide oxides are of interest in the semiconductor community for potential applications in low-dimensional electronics and photonics due to their tunable bandgap and layered crystal structure.
