MgWO3
MgWO3 is a metastable semiconducting oxide composed of magnesium, tungsten, and oxygen.

About MgWO3
MgWO3 is a complex oxide featuring magnesium and tungsten. As a semiconducting material, it represents an interesting subject for solid-state research due to its electronic properties and the variety of structural configurations it can adopt.
Because it exists in a metastable state, this compound requires specific synthesis conditions to stabilize its crystalline lattice. Its existence across multiple databases highlights its significance as a target for computational and experimental investigation into non-equilibrium material phases.
Key Properties
Cross-validated computational properties for MgWO3, 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.
