TaInO4
TaInO4 is a thermodynamically stable, wide-band-gap oxide utilized in materials science research for its insulating properties.
About TaInO4
TaInO4 is a stable ternary oxide that sits firmly on the convex hull, indicating robust thermodynamic favorability. As a wide-band-gap material, it functions primarily as an insulator, distinguishing it from the more conductive members of the transparent conducting oxide family.
Its structural characteristics are well-documented across multiple databases, reflecting significant interest in its potential for specialized electronic applications. The material's stability makes it a reliable candidate for research into oxide-based thin films and dielectric components.
Key Properties
Cross-validated computational properties for TaInO4, 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.

How It Compares
Within the transparent conducting oxides class.
While many transparent conducting oxides like ZnO are prized for their high electrical conductivity, TaInO4 occupies a different functional niche as a wide-gap insulator. Unlike the semiconducting ZnGa2O4 or the conductive BaSnO3, TaInO4 is better suited for applications requiring high dielectric performance rather than charge transport.
