Nb2TaTi
Nb2TaTi is a semimetallic ternary intermetallic alloy composed of transition metals.
About Nb2TaTi
Nb2TaTi is a complex ternary intermetallic compound composed of niobium, tantalum, and titanium. Its electronic character is defined as a near-zero-gap semimetal, placing it in a unique position between metallic conductors and semiconductors.
Due to its position above the thermodynamic hull, this material is considered metastable, which presents challenges for synthesis and long-term structural integrity. Despite this, it remains a subject of interest for researchers investigating the phase stability of refractory metal alloys.
Key Properties
Cross-validated computational properties for Nb2TaTi, 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.
