BaNa2Sr
BaNa2Sr is a semiconducting intermetallic compound containing barium, sodium, and strontium that is currently of interest for its structural complexity.
About BaNa2Sr
BaNa2Sr is a complex intermetallic compound composed of barium, sodium, and strontium. As a semiconducting material, it represents a specialized niche in inorganic chemistry where the arrangement of alkaline earth and alkali metals creates distinct electronic environments.
Because it exists above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Its existence across multiple structural configurations in database records highlights its significance as a subject of ongoing theoretical and experimental investigation in materials science.
Key Properties
Cross-validated computational properties for BaNa2Sr, 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.
