RbAuO
RbAuO is a thermodynamically stable semiconducting ternary oxide consisting of rubidium, gold, and oxygen.

About RbAuO
RbAuO is a distinct ternary oxide composed of rubidium, gold, and oxygen. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase within its chemical system, offering a unique structural arrangement that warrants further investigation in solid-state chemistry.
This material exhibits semiconducting electronic character, positioning it as an interesting candidate for research into electronic and optoelectronic applications. Its existence across multiple reported structures highlights its significance as a well-defined phase in the study of gold-based oxides.
Key Properties
Cross-validated computational properties for RbAuO, 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.
