RbC2
RbC2 is a semimetallic rubidium-carbon compound that exists in a metastable state.
About RbC2
RbC2 is a binary compound composed of rubidium and carbon. It exhibits a near-zero-gap electronic character, positioning it as a semimetallic material with unique charge-carrier dynamics.
Due to its position above the thermodynamic hull, this compound is considered metastable. Despite this, it remains a subject of interest in structural research, with numerous reported configurations documented across materials databases.
Key Properties
Cross-validated computational properties for RbC2, 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.
