About Ca4Mg2Zn2
Ca4Mg2Zn2 is a complex intermetallic compound composed of calcium, magnesium, and zinc. It exhibits semiconducting electronic behavior, marking it as a unique candidate for investigations into how ternary metal combinations influence charge transport properties. The material is characterized by significant structural diversity, with numerous reported configurations across various databases. Because it resides above the thermodynamic hull, it is considered a metastable phase, which provides valuable insights into the kinetic pathways and synthesis challenges associated with multi-element metallic systems.
Key Properties
Cross-validated computational properties for Ca4Mg2Zn2, 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.
