Sr4S3O
Sr4S3O is a semiconducting strontium oxysulfide compound that exists in a metastable state.
About Sr4S3O
Sr4S3O is a complex strontium-based oxysulfide that exhibits semiconducting electronic properties. Its unique composition of strontium, sulfur, and oxygen places it in a specialized category of inorganic compounds often explored for their potential in optoelectronic applications.
While this material has been identified in multiple structural configurations across various databases, it is characterized as being thermodynamically unstable relative to the ground state. This meta-stable nature makes it a subject of significant interest for researchers investigating phase formation and synthetic pathways in complex chalcogenide systems.
Key Properties
Cross-validated computational properties for Sr4S3O, 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.
