NbSeBr3 is a thermodynamically stable semiconducting inorganic compound composed of niobium, selenium, and bromine.
About NbSeBr3
NbSeBr3 is a semiconducting material characterized by its thermodynamic stability, positioning it as a robust candidate for further investigation. Its unique composition of niobium, selenium, and bromine suggests potential for specialized electronic applications where stable, non-metallic behavior is required.
As a material with multiple reported structural variations, it represents a versatile entry in the landscape of inorganic compounds. Its stability on the convex hull makes it a reliable subject for researchers looking to explore the intersection of transition metal chalcogenides and halides.
Key Properties
Cross-validated computational properties for NbSeBr3, aggregated across 4 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.
