MgV2In2O8
MgV2In2O8 is a semiconducting quaternary oxide characterized by its metastable nature and structural diversity.
About MgV2In2O8
MgV2In2O8 is a complex quaternary oxide composed of magnesium, vanadium, indium, and oxygen. As a semiconducting material, it represents a specialized configuration within the broader landscape of mixed-metal oxides, drawing interest for its unique elemental combination and potential electronic properties.
Despite its structural diversity, with multiple reported configurations documented in research databases, this compound is identified as being above the thermodynamic hull. This suggests that it exists as a metastable phase, which is a critical consideration for researchers evaluating its synthesis feasibility and long-term stability in practical environments.
Key Properties
Cross-validated computational properties for MgV2In2O8, 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.
