Key Properties
Cross-validated computational properties for Rb2SnO3, 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 Rb2SnO3. Tight agreement means computed properties can be trusted without re-running calculations.

How It Compares
Within the transparent conducting oxides class.
Within the broader class of transparent conducting oxides, Rb2SnO3 stands apart from well-known industrial standards like ZnO and BaSnO3 due to its specific stoichiometry and alkali-metal-based composition. While many members of this class are optimized for high conductivity, Rb2SnO3 provides a different structural template that complements the diverse array of binary and ternary oxides such as ZnGa2O4 and CaIn2O4.
