Key Properties
Cross-validated computational properties for Nb2Ga, 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.
Metallic / not reported
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.

Frequently Asked Questions
Common questions about Nb2Ga, answered from cross-validated data.
What is the band gap of Nb2Ga?
The reported DFT structures of Nb2Ga show no band gap. Standard DFT often misses gaps (especially in transition-metal oxides), so this is not proof the real material is a metal.
More questions
Is Nb2Ga a metal, semiconductor, or insulator?
DFT calculations predict no band gap. Standard DFT can miss gaps, so measurements are needed to confirm metallic behavior.
Is Nb2Ga thermodynamically stable?
Nb2Ga has a lowest energy above hull of 0.647 eV/atom (above hull).
How many polymorphs of Nb2Ga are known?
77 structures of Nb2Ga are reported across 2 databases, spanning 15 distinct space groups.
What elements does Nb2Ga contain?
Nb2Ga contains Ga and Nb (2 elements).
Where does the data for Nb2Ga come from?
Nb2Ga data is cross-referenced from latticegraph.
