About Mg3MnTe4
Mg3MnTe4 is a semiconducting ternary telluride that sits near the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis. Its electronic character positions it as a potential material for specialized semiconductor research where magnesium and manganese integration is required. The compound represents a unique intersection of alkaline earth and transition metal chalcogenide chemistry, offering a distinct structural framework for exploring electronic properties. Given its status as a near-hull phase, it is considered a target of interest for materials scientists looking to expand the library of functional semiconducting compounds.
Key Properties
Cross-validated computational properties for Mg3MnTe4, 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.
