MgV4Ag2O11 is a complex, metastable semiconducting oxide containing magnesium, silver, and vanadium.
About MgV4Ag2O11
MgV4Ag2O11 is a complex multicomponent oxide featuring magnesium, silver, and vanadium. As a semiconducting material, it represents a unique arrangement of transition metal and alkaline earth elements within an oxygen-coordinated framework.
Because it exists above the thermodynamic stability hull, this compound is considered metastable. Its existence across multiple reported structures highlights the intricate nature of its phase space and the challenges involved in its synthesis and characterization.
Key Properties
Cross-validated computational properties for MgV4Ag2O11, 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.
