InHO2
InHO2 is a semiconducting oxide material being investigated for its potential utility in transparent electronic and optoelectronic devices.
About InHO2
InHO2 is a semiconducting oxide that belongs to the broader family of transparent conducting oxides. Its position near the thermodynamic stability hull suggests that it is a viable candidate for experimental synthesis and integration into functional material systems.
As a member of this electronic class, the compound is of interest for its potential to balance optical transparency with electrical conductivity. Researchers study such materials to push the boundaries of thin-film electronics and next-generation display technologies.
Key Properties
Cross-validated computational properties for InHO2, 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 InHO2. 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.
Reported Structures
