Ba2Br1Sb1
Ba2Br1Sb1 is a semiconducting ternary compound of barium, bromine, and antimony that exhibits a wide range of structural possibilities.
About Ba2Br1Sb1
Ba2Br1Sb1 is a complex ternary compound composed of barium, bromine, and antimony. As a semiconducting material, it represents an interesting subject for researchers investigating the interplay between heavy alkaline earth metals and pnictogens within a halide framework.
Despite the existence of numerous reported structural configurations, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized in various forms, it may require specific conditions to maintain stability compared to more naturally occurring ground-state phases.
Key Properties
Cross-validated computational properties for Ba2Br1Sb1, aggregated across 2 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.
