Bi4O7
Bi4O7 is a thermodynamically stable bismuth oxide semiconductor used in materials science research.
About Bi4O7
Bi4O7 is a distinct bismuth-based oxide that occupies a stable position on the thermodynamic convex hull. As a semiconducting material, it represents a unique stoichiometry within the bismuth-oxygen binary system, characterized by a well-defined structural framework that has been documented across multiple experimental and computational databases. Its stable nature makes it a subject of interest for researchers investigating the electronic and optoelectronic properties of heavy-metal oxides. The material's ability to maintain structural integrity under various conditions suggests potential utility in specialized electronic components where bismuth-rich phases are required. Its electronic character positions it as a candidate for further exploration in semiconductor device physics.
Key Properties
Cross-validated computational properties for Bi4O7, 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.
