About Ti4Bi2O11
Ti4Bi2O11 is a complex perovskite oxide featuring bismuth and titanium. Its semiconducting electronic character and near-hull thermodynamic stability suggest it is a viable target for experimental synthesis and characterization within the broader landscape of functional oxides.
This material is of interest for its potential integration into electronic and optoelectronic devices where specific semiconducting properties are required. Its structural complexity, supported by multiple reported configurations, positions it as a significant subject for researchers exploring non-traditional perovskite architectures.
Key Properties
Cross-validated computational properties for Ti4Bi2O11, 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 widely utilized ferroelectric BaTiO3 or the magnetic transition metal perovskites like LaMnO3 and LaFeO3, Ti4Bi2O11 occupies a niche within the perovskite family due to its unique stoichiometry. While many class members like LaAlO3 serve as standard substrates or insulators, this compound offers a distinct semiconducting profile that differentiates it from the highly studied rare-earth-based variants.
