GaHO2
gallium oxide hydroxide · gallium oxyhydroxide
GaHO2 is a stable gallium-based oxide hydroxide characterized by its wide-band-gap insulating nature.
About gallium oxide hydroxide
GaHO2 is a thermodynamically stable oxide hydroxide that functions primarily as a wide-band-gap insulator. Its structural integrity and electronic properties make it a subject of interest for researchers investigating the fundamental limits of transparent conducting materials.
Because it sits reliably on the convex hull, this compound serves as a robust candidate for material synthesis studies. It is frequently examined alongside other complex oxides to understand how hydrogen incorporation influences the electronic and optical behavior of gallium-based systems.
Key Properties
Cross-validated computational properties for gallium oxide hydroxide, 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 GaHO2. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
