RbAs
RbAs is a stable, semiconducting binary compound composed of rubidium and arsenic.
About RbAs
RbAs is a binary arsenide characterized by its semiconducting electronic nature. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of rubidium and arsenic atoms that maintains integrity under standard conditions. The compound has garnered significant research interest, evidenced by its presence in multiple structural databases across numerous reported configurations. Its stability and electronic properties make it a subject of fundamental study for understanding alkali metal pnictide behavior. By providing a stable platform for investigating charge transport in binary systems, RbAs serves as a valuable reference point for researchers exploring the broader landscape of semiconducting pnictides.
Key Properties
Cross-validated computational properties for RbAs, 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.
