Ba2CdNa
Ba2CdNa is a semiconducting ternary intermetallic compound that exhibits metastable characteristics.
About Ba2CdNa
Ba2CdNa is a complex ternary intermetallic compound characterized by its semiconducting electronic behavior. Its composition, involving barium, cadmium, and sodium, places it in a unique structural category where electronic properties are highly sensitive to atomic arrangement.
Due to its position above the thermodynamic hull, this material is considered metastable, which makes it a subject of interest for researchers studying phase stability and synthesis pathways. Its existence across multiple structural databases highlights its role as a notable, albeit challenging, target for computational materials design.
Key Properties
Cross-validated computational properties for Ba2CdNa, 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.
