Se4 Nb4 I4
semiconductor· Se4 Nb4 I4
Se₄Nb₄I₄ is a mixed-halide niobium selenide compound belonging to the family of layered transition metal chalcohalides, which are emerging semiconductor materials with low-dimensional crystal structures. This material is primarily of research interest for next-generation optoelectronic and energy conversion applications, where its tunable bandgap, potential for strong light-matter interaction, and layered geometry make it attractive as an alternative to conventional semiconductors; however, it remains in early-stage development with limited commercial deployment and is less established than mature semiconductors like Si or GaAs.
