SrO3
SrO3 is a metastable, semiconducting strontium oxide that exhibits a wide array of structural configurations.

About SrO3
SrO3 is a complex strontium-oxygen compound characterized by its semiconducting electronic nature. Due to its position above the thermodynamic hull, it is considered a metastable material that requires specific synthesis conditions to be realized.
This compound is a subject of significant interest in materials science research, particularly for its structural diversity. With numerous reported structures, it serves as a valuable model for understanding high-pressure or non-equilibrium phases in alkaline earth oxides.
Key Properties
Cross-validated computational properties for SrO3, 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.
