Ca2Mg2Zn4
Ca2Mg2Zn4 is a semimetallic ternary intermetallic compound that exhibits high structural complexity and thermodynamic metastability.
About Ca2Mg2Zn4
Ca2Mg2Zn4 is a multicomponent intermetallic compound composed of calcium, magnesium, and zinc. Its electronic structure exhibits semimetallic behavior, placing it in a unique regime where metallic and semiconducting properties converge. The material is notable for its significant structural complexity, as evidenced by the large number of reported configurations across various databases. Because it resides above the thermodynamic hull, it is considered a metastable phase that requires specific synthesis conditions to stabilize.
Key Properties
Cross-validated computational properties for Ca2Mg2Zn4, 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.
