Mg2CoSbO6
Mg2CoSbO6 is a semiconducting quaternary oxide composed of magnesium, cobalt, antimony, and oxygen that is currently being studied for its structural and electronic characteristics.
About Mg2CoSbO6
Mg2CoSbO6 is a complex quaternary oxide containing magnesium, cobalt, antimony, and oxygen. As a semiconducting material, it represents a specialized composition often investigated for its unique electronic properties and potential for functional applications in solid-state devices.
While this compound has been documented across multiple structural databases, its thermodynamic profile indicates it sits above the stability hull. This suggests that the material is metastable, requiring specific synthesis conditions to stabilize its crystalline framework for experimental study.
Key Properties
Cross-validated computational properties for Mg2CoSbO6, 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.
