NbSeI3

NbSeI₃ is a layered ternary metal halide compound combining niobium, selenium, and iodine. This is a research-stage material studied primarily for its potential in optoelectronic and electronic applications, particularly in areas where layered crystal structures enable anisotropic properties or tunable band gaps. The material belongs to a family of transition metal halides attracting attention for semiconducting behavior, photovoltaic response, and potential applications in 2D materials science, though industrial production and deployment remain limited.
