Hg2BrN
Hg2BrN is a metastable, semiconducting inorganic compound composed of mercury, bromine, and nitrogen.
About Hg2BrN
Hg2BrN is a complex inorganic compound containing mercury, bromine, and nitrogen. As a semiconducting material, it exhibits electronic properties that bridge the gap between conductive metals and insulating materials, making it a subject of interest for fundamental solid-state research.
Despite its existence in multiple structural forms across various databases, the compound is characterized by a thermodynamic state that sits above the hull. This suggests that it is a metastable phase, requiring specific synthesis conditions to stabilize its configuration for potential experimental evaluation.
Key Properties
Cross-validated computational properties for Hg2BrN, 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.
