HgN3
HgN3 is a semiconducting mercury-nitrogen compound that exhibits significant structural diversity despite being thermodynamically unstable.
About HgN3
HgN3 is a semiconducting compound composed of mercury and nitrogen. It represents a complex chemical system, characterized by a significant number of reported structural configurations across scientific databases, reflecting a high degree of interest in its atomic arrangement.
Due to its position above the thermodynamic hull, this material is considered inherently unstable. Its electronic character as a semiconductor makes it a subject of fundamental study for researchers investigating the limits of mercury-nitrogen bonding and the potential for metastable phases.
Key Properties
Cross-validated computational properties for HgN3, 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.
