About Br7STa3
Br7STa3 is a complex inorganic compound composed of tantalum, sulfur, and bromine. Its semiconducting electronic character makes it an intriguing candidate for specialized solid-state applications where precise charge transport properties are required.
As a near-hull stable material, it is considered likely synthesizable under controlled experimental conditions. The existence of multiple reported structures across databases highlights its potential for structural diversity and its role as a subject of interest in exploratory materials science.
Key Properties
Cross-validated computational properties for Br7STa3, 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.
