Key Properties
Cross-validated computational properties for Ca2Sn3O8, 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.

How It Compares
Within the perovskite oxides class.
Unlike the more widely characterized perovskites such as BaTiO3 or the magnetic transition-metal oxides like LaMnO3 and LaFeO3, Ca2Sn3O8 occupies a niche space defined by its unique calcium-tin composition. While materials like LaAlO3 are frequently used as stable substrates, Ca2Sn3O8 offers a distinct electronic profile that differentiates it from the highly metallic LaNiO3 or the multiferroic BiFeO3, positioning it as an intriguing alternative for specialized semiconducting applications.
