Mg2Sb2
Mg2Sb2 is a metastable metallic intermetallic compound composed of magnesium and antimony that exhibits significant structural complexity.
About Mg2Sb2
Mg2Sb2 is a metastable metallic compound composed of magnesium and antimony. Its electronic character is defined by its metallic nature, lacking a band gap, which distinguishes it from traditional semiconducting pnictides often found in this chemical family. The material is characterized by significant structural diversity, with numerous reported configurations across multiple databases. This high degree of structural complexity makes it a compelling subject for researchers investigating phase stability and the formation of metastable intermetallic phases.
Key Properties
Cross-validated computational properties for Mg2Sb2, aggregated across 4 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.
