F2OTe
F2OTe is a thermodynamically stable, wide-gap insulating compound containing tellurium, oxygen, and fluorine.
About F2OTe
F2OTe is a distinct inorganic compound composed of tellurium, oxygen, and fluorine. As a thermodynamically stable phase residing on the convex hull, it represents a robust chemical configuration within its elemental system.
Characterized as a wide-gap insulator, this material possesses electronic properties typical of highly stable dielectric substances. Its structural diversity, evidenced by multiple reported configurations, makes it a subject of interest for fundamental solid-state research.
Key Properties
Cross-validated computational properties for F2OTe, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
