About ZrI3
ZrI3 is a semiconducting compound composed of zirconium and iodine. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration within the zirconium-iodide system. Its electronic character suggests potential utility in specialized semiconductor applications where specific band structures are required.
Given its status as a well-documented material with numerous reported structures across multiple databases, ZrI3 serves as a significant subject for structural research. Its stability and composition make it an intriguing candidate for investigations into low-dimensional electronic materials and solid-state chemistry.
Key Properties
Cross-validated computational properties for ZrI3, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
