RbAgO is a thermodynamically stable, semiconducting ternary oxide known for its structural complexity and potential utility in materials science research.
About RbAgO
RbAgO is a distinct ternary oxide that occupies a stable position on the thermodynamic convex hull. As a semiconducting material, it represents an intriguing intersection of alkali metal chemistry and transition metal oxides, offering unique electronic pathways that are of significant interest for fundamental solid-state studies.
The compound is characterized by a notable structural diversity, with multiple reported configurations across various databases. This structural richness suggests that RbAgO possesses a complex coordination environment, making it a valuable subject for researchers investigating the interplay between silver-oxygen bonding and rubidium-based lattice stabilization.
Key Properties
Cross-validated computational properties for RbAgO, 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.
