TaBiO4 is a thermodynamically stable semiconducting perovskite oxide used in materials science research.

About TaBiO4
TaBiO4 is a stable member of the perovskite oxide family, characterized by its semiconducting electronic nature. Its position on the convex hull suggests a robust structural integrity that makes it a compelling subject for materials research and development in oxide electronics. The compound benefits from a rich set of reported structural data, providing a solid foundation for understanding its behavior in various solid-state environments. Its unique combination of bismuth and tantalum within an oxide framework positions it as a specialized candidate for functional material design.
Key Properties
Cross-validated computational properties for TaBiO4, 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 perovskite oxides class.
While classic perovskites like BaTiO3 are widely utilized for their ferroelectric and dielectric properties, TaBiO4 distinguishes itself as a stable semiconducting alternative. Unlike the transition-metal-heavy systems such as LaNiO3 or LaMnO3, which are often investigated for their magnetic and metallic transitions, TaBiO4 offers a different electronic landscape that complements the insulating nature of materials like LaAlO3.
