NbTiW2
NbTiW2 is a semimetallic ternary alloy composed of niobium, titanium, and tungsten that exists in a metastable state.
About NbTiW2
NbTiW2 is a ternary metallic compound composed of niobium, titanium, and tungsten. Characterized by a near-zero band gap, this material exhibits semimetallic electronic behavior that is of significant interest for fundamental condensed matter research. Its structural complexity is reflected in the multiple distinct configurations reported across various materials databases. As a metastable phase residing above the thermodynamic hull, NbTiW2 represents a challenging target for synthesis and stabilization. Its unique elemental combination makes it a subject of interest for exploring high-entropy or refractory alloy systems where structural stability and electronic properties are delicately balanced.
Key Properties
Cross-validated computational properties for NbTiW2, 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.

How It Compares
As a ternary system containing refractory elements, NbTiW2 occupies a specialized niche in materials science where its semimetallic nature distinguishes it from more common insulating or purely metallic alloys. Without direct structural siblings in its immediate class, it serves as a critical case study for understanding how the integration of niobium, titanium, and tungsten influences phase stability and electronic density of states in complex metallic systems.
