BaSi
BaSi is a thermodynamically stable, metallic silicide that serves as a structurally diverse candidate for advanced anode material research.
About BaSi
BaSi is a metallic silicide that sits firmly on the convex hull, indicating high thermodynamic stability. As a member of the silicon anode material class, it represents a robust structural candidate for electrochemical applications where electronic conductivity is a primary requirement.
With a significant number of reported structures across various databases, this compound is a well-characterized material. Its metallic nature distinguishes it from many semiconductor-based silicides, making it an interesting subject for studies focusing on charge transport and structural phase stability.
Key Properties
Cross-validated computational properties for BaSi, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
