About Pb2O3
Pb2O3 is a semiconducting oxide of lead that exists as a complex structural system. Its classification as a near-hull material suggests that it is a metastable phase capable of being synthesized under specific experimental conditions, making it a subject of significant interest for solid-state chemistry studies.
With a high degree of structural diversity reported across multiple databases, this compound serves as a critical model for understanding lead-oxygen bonding environments. Its electronic character positions it as a candidate for specialized applications where semiconducting lead-based materials are required for their unique optoelectronic properties.
Key Properties
Cross-validated computational properties for Pb2O3, aggregated across 4 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.
