Mg2VBiO6
Mg2VBiO6 is a complex, wide-gap insulating oxide that is predicted to be stable enough for successful laboratory synthesis.
About Mg2VBiO6
Mg2VBiO6 is a complex quaternary oxide composed of magnesium, vanadium, bismuth, and oxygen. As a wide-gap insulator, it exhibits electronic properties characteristic of stable dielectric materials, positioning it as an interesting subject for materials discovery efforts.
Its status as a near-hull phase suggests that it is likely synthesizable under standard laboratory conditions. The existence of multiple reported structural configurations indicates a rich potential for polymorphism, which is vital for understanding its structural stability and future functional utility.
Key Properties
Cross-validated computational properties for Mg2VBiO6, 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.
