Bi2O4Sr2
Bi2O4Sr2 is a stable, semiconducting bismuth strontium oxide used in materials research.
About Bi2O4Sr2
Bi2O4Sr2 is a complex oxide composed of bismuth, strontium, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within its chemical system. Its electronic character as a semiconductor makes it an interesting candidate for materials science investigations where tunable conductivity is required. The compound is characterized by a well-defined structural framework that has been documented in crystallographic databases. Its stability suggests potential for integration into functional devices where long-term structural integrity is a primary design constraint.
Key Properties
Cross-validated computational properties for Bi2O4Sr2, 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.
