Key Properties
Cross-validated computational properties for TaTe2, 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.
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 TaTe2, answered from cross-validated data.
What is the band gap of TaTe2?
The reported DFT structures of TaTe2 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 TaTe2 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 TaTe2 thermodynamically stable?
Yes — TaTe2 sits on the convex hull (energy above hull 0 eV/atom), i.e. on hull (stable).
How many polymorphs of TaTe2 are known?
89 structures of TaTe2 are reported across 5 databases, spanning 18 distinct space groups.
What elements does TaTe2 contain?
TaTe2 contains Ta and Te (2 elements).
Where does the data for TaTe2 come from?
TaTe2 data is cross-referenced from latticegraph.
