Its electronic nature makes it a subject of interest for fundamental studies in solid-state physics and materials science.
With a significant number of reported structures across major databases, this compound is well-documented in the scientific literature. Its stability and semiconducting behavior suggest potential utility in specialized electronic or optoelectronic applications where specific halide-based structural frameworks are required.
Key Properties
Cross-validated computational properties for InI2, 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.
