Key Properties
Cross-validated computational properties for Nd3TaO7, 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.

How It Compares
Within the perovskite oxides class.
Unlike the highly conductive or magnetic transition-metal perovskites such as LaNiO3 and LaMnO3, Nd3TaO7 is defined by its wide-gap insulating behavior. While many members of this class, including BaTiO3 and BiFeO3, are widely recognized for their ferroelectric or multiferroic properties, Nd3TaO7 occupies a niche as a stable, insulating structural framework that contrasts with the more electronically active lanthanum-based perovskites like LaFeO3 or LaCoO3.
