NbBi3O7
NbBi3O7 is a semiconducting perovskite oxide that is considered a promising candidate for synthesis due to its favorable thermodynamic stability.
About NbBi3O7
NbBi3O7 is a semiconducting member of the perovskite oxide family, characterized by its complex structural arrangement of niobium, bismuth, and oxygen. Its thermodynamic profile places it near the stability hull, suggesting it is a viable candidate for experimental synthesis and characterization.
This compound is of significant interest to materials scientists investigating the electronic properties of bismuth-based oxides. Given its semiconducting nature, it serves as a platform for exploring functional materials that could be integrated into future electronic or optoelectronic devices.
Key Properties
Cross-validated computational properties for NbBi3O7, 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.

How It Compares
Within the perovskite oxides class.
Unlike the well-established ferroelectric BiFeO3 or the widely utilized dielectric BaTiO3, NbBi3O7 represents a more specialized niche within the perovskite oxide class. While compounds like LaNiO3 and LaMnO3 are frequently studied for their magnetic and metallic properties, NbBi3O7 is distinguished by its specific semiconducting behavior and potential for structural diversity, as evidenced by the multiple reported structural configurations.
