InHO
InHO is a thermodynamically stable indium-based oxide that functions as a wide-gap insulator within the transparent conducting oxide material class.
About InHO
InHO is a thermodynamically stable inorganic compound that sits firmly on the convex hull, indicating robust structural integrity. As a member of the transparent conducting oxide class, it exhibits wide-gap insulating characteristics that distinguish its electronic behavior in thin-film applications. Its presence across multiple structural databases highlights its significance as a subject of ongoing materials research. This compound serves as a critical building block for understanding indium-based oxide systems, particularly where high stability is required for electronic or optical components. Its unique electronic profile makes it a compelling candidate for specialized semiconductor development where traditional transparent conductors may require modification.
Key Properties
Cross-validated computational properties for InHO, 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.
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 InHO. 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.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
