HoNbO4
HoNbO4 is a stable, insulating crystalline oxide containing holmium and niobium.
About HoNbO4
HoNbO4 is a complex oxide composed of holmium, niobium, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions.
This material functions as a wide-band-gap insulator, a characteristic that makes it a subject of interest for dielectric and optical applications. With multiple reported structures, it offers a versatile framework for studying rare-earth niobate behavior.
Key Properties
Cross-validated computational properties for HoNbO4, 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.
