MgTiO2
MgTiO2 is a semiconducting magnesium-titanium oxide that exists in multiple structural forms but is generally considered thermodynamically unstable.
About MgTiO2
MgTiO2 is a complex oxide material composed of magnesium, titanium, and oxygen. As a semiconducting compound, it represents an interesting subject for researchers investigating electronic properties within ternary oxide systems.
Despite its existence in multiple structural configurations across various databases, the material is characterized by its position above the thermodynamic hull. This suggests that it may be difficult to synthesize or maintain in a stable state under standard conditions compared to more common binary oxides.
Key Properties
Cross-validated computational properties for MgTiO2, 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.
