H3NO4
H3NO4 is a thermodynamically stable, insulating compound composed of hydrogen, nitrogen, and oxygen.

About H3NO4
H3NO4 is a distinct inorganic compound characterized by its insulating electronic nature and wide band gap. As a thermodynamically stable material residing on the convex hull, it represents a robust configuration of hydrogen, nitrogen, and oxygen atoms.
Its structural diversity is highlighted by numerous reported configurations across multiple databases. This complexity makes it a subject of interest for researchers investigating stable, non-conductive chemical systems.
Key Properties
Cross-validated computational properties for H3NO4, 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.
