MnNb2Re
MnNb2Re is a semimetallic ternary compound containing manganese, niobium, and rhenium that is currently considered thermodynamically unstable.
About MnNb2Re
MnNb2Re is a complex ternary intermetallic compound composed of manganese, niobium, and rhenium. Its electronic structure is characterized as a near-zero-gap semimetallic system, which places it in a unique position for studying charge carrier dynamics in transition metal alloys.
Despite its interesting electronic profile, the material is identified as being above the thermodynamic hull. This suggests that the phase is likely unstable under standard conditions, which explains why it remains a subject of theoretical and structural investigation rather than widespread industrial implementation.
Key Properties
Cross-validated computational properties for MnNb2Re, 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.
