Nb4 Se4 I12

Nb₄Se₄I₁₂ is a layered mixed-halide semiconductor compound combining niobium, selenium, and iodine—a material family of interest primarily in research and emerging photonic applications rather than established industrial production. This compound represents the broader class of halide perovskites and transition-metal chalcogenide semiconductors, which are being investigated for optoelectronic devices where tunable bandgaps and low-dimensional electronic structure offer advantages over conventional semiconductors. While not yet commercialized at scale, materials in this family show potential for next-generation photovoltaics, light-emission, and radiation detection where layer-dependent properties and chemical modularity can be engineered for specific performance targets.
