Ga4O8Pb2
Ga4O8Pb2 is a thermodynamically stable, wide-gap insulating oxide containing gallium, lead, and oxygen.
About Ga4O8Pb2
Ga4O8Pb2 is a complex oxide composed of gallium, lead, and oxygen that sits firmly on the convex hull, indicating high thermodynamic stability. Its electronic structure is defined by a wide band gap, classifying it as an insulator rather than a traditional conductor.
This material is of significant interest in materials science due to its structural diversity, with multiple reported crystal configurations across databases. Its insulating nature makes it a candidate for specialized dielectric applications where stable, wide-gap oxide frameworks are required.
Key Properties
Cross-validated computational properties for Ga4O8Pb2, 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.
