MnV
MnV is a stable, metallic binary compound formed from manganese and vanadium that is widely documented in structural databases.
About MnV
MnV is a binary metallic compound composed of manganese and vanadium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration within the manganese-vanadium system. Its metallic nature suggests significant potential for electronic and magnetic applications where conductivity is a primary requirement.
With a high degree of data richness across multiple structural databases, this compound serves as a key reference point for researchers studying transition metal alloys. Its stability makes it an ideal candidate for further investigation into phase transformation and alloying behavior in high-performance metallic systems.
Key Properties
Cross-validated computational properties for MnV, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of MnV. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
