Sr4I6O
Sr4I6O is a stable, wide-gap insulating compound composed of strontium, iodine, and oxygen.
About Sr4I6O
Sr4I6O is a distinct strontium-based oxyiodide that exists as a thermodynamically stable phase on the convex hull. Its electronic character is defined by a wide band gap, classifying it as an insulator with significant structural integrity.
This compound represents an interesting intersection of alkaline earth metal chemistry and halide-oxide systems. Due to its stability and insulating nature, it serves as a foundational material for researchers investigating complex inorganic lattices and dielectric properties.
Key Properties
Cross-validated computational properties for Sr4I6O, 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.
