Ca2MgCd is a stable, semimetallic ternary intermetallic compound composed of calcium, magnesium, and cadmium.
About Ca2MgCd
Ca2MgCd is a ternary intermetallic compound composed of calcium, magnesium, and cadmium. It exhibits a semimetallic electronic character, placing it in a unique position between traditional metals and semiconductors, which makes it a subject of interest for fundamental solid-state physics investigations.
Positioned near the thermodynamic hull, this material is considered a likely candidate for experimental synthesis. Its existence across multiple structural databases highlights its significance as a stable, well-characterized phase within the calcium-magnesium-cadmium ternary system.
Key Properties
Cross-validated computational properties for Ca2MgCd, 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.
