H3O2
H3O2 is a metastable, insulating compound composed of hydrogen and oxygen atoms that exhibits significant structural complexity.
About H3O2
H3O2 is a hydrogen-oxygen compound that exists in a metastable state. Its electronic character is defined by a wide band gap, classifying it as an insulating material rather than a conductor or semiconductor. Due to its unique composition, it remains a subject of interest in fundamental chemical studies where hydrogen-oxygen bonding dynamics are explored. The material is characterized by a high degree of structural diversity, with numerous configurations reported in scientific databases. This structural variety highlights the complex nature of its atomic arrangements under varying conditions.
Key Properties
Cross-validated computational properties for H3O2, aggregated across 2 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.
