TaNF2
TaNF2 is a semiconducting tantalum nitrogen fluoride that exists as a metastable phase within the landscape of inorganic compounds.
About TaNF2
TaNF2 is a complex inorganic compound composed of tantalum, nitrogen, and fluorine. As a semiconducting material, it represents a unique intersection of transition metal chemistry and halide-nitride bonding, providing a specialized subject for solid-state research. Due to its position above the thermodynamic hull, TaNF2 is considered a metastable phase. Its existence across multiple reported structures highlights the intricate structural landscape of tantalum-based nitrogen fluorides, making it a target for synthesis studies aimed at stabilizing novel electronic materials.
Key Properties
Cross-validated computational properties for TaNF2, 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.
