Na3IO
Na3IO is a semiconducting ternary oxide containing sodium and iodine that is considered potentially synthesizable due to its favorable thermodynamic stability.
About Na3IO
Na3IO is a ternary compound consisting of sodium, iodine, and oxygen. As a semiconducting material, it occupies a unique position in inorganic chemistry, bridging the properties of simple oxides and halide-based systems.
Its status as a near-hull phase suggests that it is thermodynamically accessible for experimental synthesis. The existence of multiple structural variations in databases highlights its potential for polymorphic behavior and complex bonding arrangements.
Key Properties
Cross-validated computational properties for Na3IO, 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.
