Gold(I) bromide is a stable, semiconducting inorganic compound consisting of gold and bromine atoms.
About Gold(I) bromide
Gold(I) bromide is a binary inorganic compound composed of gold and bromine. As a thermodynamically stable phase residing on the convex hull, it represents a well-defined stoichiometric arrangement that has been extensively characterized across numerous structural databases.
This material exhibits semiconducting electronic behavior, distinguishing it from more common metallic gold alloys. Its unique electronic structure makes it a subject of interest in materials science, particularly for applications requiring specific gold-halide interactions and stable semiconductor properties.
Key Properties
Cross-validated computational properties for Gold(I) bromide, 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.
