MgIn2O4
MgIn2O4 is a semiconducting transparent conducting oxide with potential utility in optoelectronic and electronic thin-film technologies.
About MgIn2O4
MgIn2O4 is a complex oxide belonging to the transparent conducting oxide class. As a semiconducting material, it exhibits electronic properties that make it a subject of interest for thin-film electronics and optoelectronic device development. Its status as a near-hull compound suggests that it is a viable candidate for experimental synthesis and structural investigation.
This material is valued for its potential to bridge the gap between traditional transparent conductors and more specialized spinel-structured oxides. By leveraging its unique elemental composition of magnesium and indium, researchers explore its utility in applications requiring a balance of optical transparency and electrical conductivity.
Key Properties
Cross-validated computational properties for MgIn2O4, 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.

How It Compares
Within the transparent conducting oxides class.
Within the diverse family of transparent conducting oxides, MgIn2O4 occupies a distinct niche compared to well-established materials like ZnO or BaSnO3. While ZnO is widely utilized for its high conductivity, MgIn2O4 offers a different structural framework as a spinel, sharing more architectural similarities with ZnGa2O4 or ZnCr2O4, which allows for different tuning of its electronic and optical properties.
