About Nb1Re2V1
Nb1Re2V1 is a complex intermetallic compound composed of niobium, rhenium, and vanadium. As a semimetallic material with a near-zero band gap, it exhibits electronic characteristics that bridge the gap between traditional metals and semiconductors, making it a subject of interest for fundamental solid-state research.
Despite its structural diversity, with numerous reported configurations across databases, the material sits above the thermodynamic hull. This suggests that the phase is likely metastable under standard conditions, requiring specific synthesis pathways to stabilize its unique atomic arrangement.
Key Properties
Cross-validated computational properties for Nb1Re2V1, aggregated across 2 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.
