CaSnO2
CaSnO2 is a metastable semiconducting perovskite oxide used primarily in fundamental materials science research.
About CaSnO2
CaSnO2 is a semiconducting member of the perovskite oxide family, characterized by its complex structural arrangements. As a metastable phase, it represents a unique configuration within the oxide landscape, offering intriguing possibilities for materials scientists investigating non-equilibrium states in perovskites.
Its electronic nature makes it a subject of interest for researchers exploring thin-film synthesis and defect engineering. While it remains a specialized material compared to more common oxides, its existence across multiple structural databases highlights its significance in fundamental condensed matter studies.
Key Properties
Cross-validated computational properties for CaSnO2, aggregated across 4 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 perovskite oxides class.
Within the broad class of perovskite oxides, CaSnO2 occupies a distinct niche compared to highly stable, widely utilized members like BaTiO3 or the versatile rare-earth-based LaMnO3. Unlike the robust ferroelectric properties found in BiFeO3 or the catalytic activity of LaCoO3, CaSnO2 is defined by its metastability, positioning it as a specialized candidate for exploratory research rather than standard industrial deployment.
