CaMgCd2
CaMgCd2 is a thermodynamically stable, semimetallic ternary intermetallic compound.
About CaMgCd2
CaMgCd2 is a ternary intermetallic compound that occupies a stable position on the convex hull, indicating significant thermodynamic robustness. Its electronic character is defined as a near-zero-gap semimetal, placing it in a distinct category of materials that bridge the gap between metallic conductors and semiconductors.
This material is of interest to researchers studying complex intermetallic phases and the structural diversity of calcium-magnesium-cadmium systems. With multiple reported structures across various databases, it serves as a foundational subject for understanding phase stability and electronic behavior in multicomponent metallic systems.
Key Properties
Cross-validated computational properties for CaMgCd2, 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.
