About TiBi2O5
TiBi2O5 is a semiconducting oxide that occupies a stable position on the thermodynamic convex hull. As a member of the perovskite-related family, it exhibits a robust structural framework that makes it a subject of interest for researchers investigating complex metal oxides with specific electronic properties. Its stability suggests potential for integration into functional device architectures where material longevity is critical. The compound is characterized by a well-defined structural profile, supported by multiple reported entries across major materials databases, highlighting its significance in the study of bismuth-titanium-based systems. It serves as a valuable candidate for exploring the interplay between transition metal d-orbitals and heavy-element bismuth cations in semiconducting oxides.
Key Properties
Cross-validated computational properties for TiBi2O5, 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.
Unlike the highly symmetric and widely utilized BaTiO3, which is a cornerstone of ferroelectric technology, TiBi2O5 represents a more specialized structural variant within the broader perovskite oxide class. While compounds like LaMnO3 or LaFeO3 are frequently studied for their magnetic and catalytic properties, TiBi2O5 offers a distinct electronic character that differentiates it from these lanthanum-based perovskites, positioning it as a unique subject for targeted semiconductor research.
