BaHIO
BaHIO is a stable, wide-gap insulating material composed of barium, hydrogen, iodine, and oxygen.
About BaHIO
BaHIO is a complex inorganic compound characterized by its insulating electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement of barium, hydrogen, iodine, and oxygen atoms.
Its stability and wide-gap electronic profile make it an intriguing subject for fundamental research. While it remains an unclassified material, its existence across multiple structural databases highlights its significance in the broader landscape of complex quaternary solids.
Key Properties
Cross-validated computational properties for BaHIO, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of BaHIO. Tight agreement means computed properties can be trusted without re-running calculations.
