Rb2As3
Rb2As3 is a stable, semiconducting binary compound formed from rubidium and arsenic.
About Rb2As3
Rb2As3 is a thermodynamically stable inorganic compound composed of rubidium and arsenic. As a member of the alkali metal arsenide family, it exhibits semiconducting electronic properties that make it a subject of interest for fundamental materials science research.
Its position on the convex hull indicates high thermodynamic stability, which is supported by its appearance across multiple structural databases. This stability makes it a reliable candidate for investigating the complex bonding environments found in binary pnictide systems.
Key Properties
Cross-validated computational properties for Rb2As3, 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.
