Na8SnO6
Na8SnO6 is a semiconducting sodium-tin oxide that belongs to the broader category of perovskite-related materials.
About Na8SnO6
Na8SnO6 is a complex oxide within the perovskite-related family, characterized by its semiconducting electronic nature. Its structural configuration suggests it is a viable target for laboratory synthesis, as indicated by its near-hull thermodynamic stability and presence in multiple structural databases.
This compound serves as an intriguing subject for materials scientists exploring non-traditional perovskite compositions. By leveraging its unique stoichiometry, researchers can investigate how alkali-rich oxide frameworks influence electronic properties compared to more conventional transition metal-based perovskites.
Key Properties
Cross-validated computational properties for Na8SnO6, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of Na8SnO6. Tight agreement means computed properties can be trusted without re-running calculations.
