Key Properties
Cross-validated computational properties for TaC, 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.
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 TaC, answered from cross-validated data.
What is the band gap of TaC?
TaC is computed to be metallic (no band gap) in the reported DFT structures.
More questions
Is TaC a metal, semiconductor, or insulator?
Computed band structures report no gap, so it is metallic.
Is TaC thermodynamically stable?
Yes — TaC sits on the convex hull (energy above hull 0 eV/atom), i.e. on hull (stable).

405 structures of TaC are reported across 4 databases, spanning 43 distinct space groups.
How is TaC synthesized?
Literature-reported routes for TaC include solid state (10 procedures documented).
What elements does TaC contain?
TaC contains C and Ta (2 elements).
