MgBC
MgBC is a stable, semiconducting ternary compound consisting of magnesium, boron, and carbon.
About MgBC
MgBC is a distinct ternary compound composed of magnesium, boron, and carbon. As a thermodynamically stable material situated on the convex hull, it represents a robust structural arrangement that has garnered significant interest across multiple materials databases.
Characterized as a semiconductor, this material bridges the gap between conventional metallic alloys and insulating ceramics. Its electronic nature makes it a compelling candidate for specialized applications where controlled charge transport is essential for device performance.
Key Properties
Cross-validated computational properties for MgBC, 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.
