Ba2MgNa
Ba2MgNa is a semiconducting intermetallic compound composed of barium, magnesium, and sodium that exhibits potential thermodynamic instability.
About Ba2MgNa
Ba2MgNa is a ternary intermetallic compound composed of barium, magnesium, and sodium. It exhibits semiconducting electronic characteristics, placing it in a distinct category of materials that bridge the gap between metallic conductors and insulating solids.
Due to its position above the thermodynamic hull, this compound is considered potentially unstable under standard conditions. Despite this, it remains a subject of interest in structural databases, with multiple reported configurations that provide insight into the complex bonding environments of alkaline earth and alkali metal systems.
Key Properties
Cross-validated computational properties for Ba2MgNa, 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.
