About Barium carbide
Barium carbide is a binary compound composed of barium and carbon. As a semiconducting material, it represents a specialized chemical system that has been the subject of extensive structural investigation across multiple databases.
While it is often found to be thermodynamically unstable relative to other phases, its complex structural landscape makes it a significant subject for researchers studying carbide chemistry and solid-state reactivity.
Key Properties
Cross-validated computational properties for Barium carbide, 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.
