PO2
PO2 is a wide-band-gap insulating phosphorus oxide that is considered a promising candidate for synthesis due to its near-stable thermodynamic profile.
About PO2
PO2 is a phosphorus oxide characterized by its insulating electronic nature and wide band gap. As a material that sits near the thermodynamic hull, it represents a compelling subject for experimental synthesis and structural investigation within the phosphorus-oxygen system. Its structural complexity is highlighted by a vast array of reported configurations across crystalline databases. The compound's proximity to stability suggests that it may be accessible under specific processing conditions, making it a point of interest for researchers exploring non-traditional phosphorus-based frameworks. Its insulating behavior positions it as a potential candidate for dielectric applications or as a component in specialized electronic thin films.
Key Properties
Cross-validated computational properties for PO2, 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.
