BaNa
BaNa is a thermodynamically stable intermetallic compound that functions as a semimetallic material.
About BaNa
BaNa is a binary intermetallic compound composed of barium and sodium. It is characterized by its thermodynamically stable nature, sitting firmly on the convex hull, which indicates a robust energetic preference for its specific atomic arrangement.
This material displays a near-zero-gap electronic structure, placing it in the semimetallic regime. With dozens of reported structures documented across various databases, it represents a highly studied system within its chemical class, offering significant insights into the bonding behavior of alkaline earth and alkali metal combinations.
Key Properties
Cross-validated computational properties for BaNa, 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.
