RbAu
RbAu is a stable, semiconducting intermetallic compound composed of rubidium and gold.
About RbAu
RbAu is a thermodynamically stable intermetallic compound that occupies a unique position on the convex hull. Its electronic character is defined as semiconducting, distinguishing it from typical metallic alloys and making it a subject of significant interest in solid-state chemistry.
Due to its structural complexity, this material has been extensively characterized across multiple databases. It serves as a critical model for understanding the interactions between alkali metals and noble metals in the solid state.
Key Properties
Cross-validated computational properties for RbAu, 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.
