MnO6SrTe is a semiconducting quaternary oxide that exists as a metastable phase within the manganese-strontium-tellurium-oxygen system.
About MnO6SrTe
MnO6SrTe is a complex quaternary oxide incorporating manganese, strontium, and tellurium. As a semiconducting material, it represents a niche composition that bridges the properties of transition metal oxides and tellurates. Its electronic character suggests potential utility in specialized optoelectronic or sensing research where specific band structures are required.
This compound is characterized by its metastable nature, existing above the thermodynamic hull. Despite its instability, it has been identified across multiple structural databases, highlighting its significance in theoretical studies of high-energy phase formation and the exploration of complex oxide synthesis pathways.
Key Properties
Cross-validated computational properties for MnO6SrTe, 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.
