As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration of aluminum, iodine, and chlorine atoms that maintains structural integrity under standard conditions. The compound is notable for its structural diversity, with multiple reported configurations across major materials databases. This versatility makes it an intriguing subject for researchers investigating the interplay between halide chemistry and semiconductor physics.
Key Properties
Cross-validated computational properties for AlICl2, 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.
