SrO4
SrO4 is a semiconducting strontium oxide phase that exhibits structural complexity and is generally considered to be thermodynamically unstable.
About SrO4
SrO4 is a strontium-oxygen compound characterized by its semiconducting electronic nature. As a complex oxide phase, it represents a specific arrangement of strontium and oxygen atoms that has been documented across various structural configurations in materials databases.
Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Its existence is primarily of interest in fundamental materials research, where understanding the formation and structural diversity of high-oxygen strontium phases remains a key objective.
Key Properties
Cross-validated computational properties for SrO4, 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.
