BaSrTl2
BaSrTl2 is a thermodynamically stable semiconducting intermetallic compound formed from barium, strontium, and thallium.
About BaSrTl2
BaSrTl2 is a distinct intermetallic compound composed of barium, strontium, and thallium. It is recognized for its thermodynamic stability, sitting directly on the convex hull, which indicates a robust structural configuration under standard conditions.
As a semiconducting material, this compound represents an interesting case for solid-state research. Its existence across multiple reported structures suggests a complex phase landscape that is highly relevant for fundamental studies in materials science and electronic behavior.
Key Properties
Cross-validated computational properties for BaSrTl2, 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.
