Sr3Ti2O7
Sr3Ti2O7 is a stable, layered perovskite oxide that functions as a semiconductor in advanced materials applications.
About Sr3Ti2O7
Sr3Ti2O7 is a member of the Ruddlesden-Popper series of perovskite oxides, characterized by its layered structural arrangement. As a thermodynamically stable compound, it maintains a robust crystalline framework that is highly valued in fundamental materials research.
This semiconducting oxide is primarily investigated for its unique electronic properties and potential integration into thin-film heterostructures. Its ability to accommodate structural variations makes it a significant subject for studies focused on dielectric and semiconducting performance in complex oxide systems.
Key Properties
Cross-validated computational properties for Sr3Ti2O7, 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.
