Its metastable nature makes it a compelling subject for synthesis research, as it offers distinct structural properties compared to more conventional, highly stable oxides. The material is primarily investigated for its role in photocatalysis, where its electronic characteristics allow it to facilitate light-driven chemical reactions. Its versatility within the spinel family positions it as a key candidate for developing next-generation functional materials.
Key Properties
Cross-validated computational properties for Zinc indium oxide, 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.
