NbSbO4 is a thermodynamically stable semiconducting oxide containing niobium and antimony.
About NbSbO4
NbSbO4 is a complex oxide composed of niobium, antimony, and oxygen. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement that is well-defined within materials databases. Its semiconducting nature makes it an intriguing subject for research into electronic and optoelectronic materials.
The compound is characterized by a high degree of structural diversity, with multiple reported configurations across various databases. This structural flexibility suggests potential for fine-tuning its physical properties for specialized technological applications where stable, semiconducting oxides are required.
Key Properties
Cross-validated computational properties for NbSbO4, 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.
