· JVASP-27233· NbTeI3

NbTeI3 is an intermetallic compound combining niobium, tellurium, and iodine, belonging to the family of transition metal chalcohalides. This material is primarily of research interest rather than established industrial production, with potential applications in solid-state electronics and thermoelectric devices where layered metal-chalcogen-halogen systems show promise for tunable electronic and phononic properties.
