CdMg2Pb
CdMg2Pb is a semiconducting ternary intermetallic compound that exists in a metastable state.
About CdMg2Pb
CdMg2Pb is a ternary intermetallic compound characterized by its semiconducting electronic nature. Its atomic arrangement is captured across multiple structural databases, reflecting a complex configuration that remains a subject of ongoing investigation in materials science.
As a material that sits above the thermodynamic hull, CdMg2Pb is considered metastable. This status makes it a compelling candidate for researchers studying phase stability and the synthesis of non-equilibrium crystalline phases in multi-element systems.
Key Properties
Cross-validated computational properties for CdMg2Pb, 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.
