As a thermodynamically stable phase residing on the convex hull, it represents a well-defined structural arrangement of gallium and bromine atoms. Its stability makes it a significant subject for researchers investigating group thirteen halides. The compound is supported by a robust body of structural data, reflecting its importance in fundamental materials research. While its specific industrial utility is niche, it serves as a critical reference point for understanding the bonding and phase behavior of gallium-based systems in solid-state chemistry.
Key Properties
Cross-validated computational properties for GaBr2, 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.
