A material class whose independent-electron or quasiparticle description has partially filled bands or band crossings at the chemical potential, permitting low-energy charged excitations. Scattering still controls finite conductivity.

This is an authored directed relation from the source endpoint to the target endpoint.
Within a band or Fermi-liquid description, a material is metallic when charged excitations remain available arbitrarily close to the chemical potential.
The target is a member or subtype of the broader source class.

This is an authored directed relation from the source endpoint to the target endpoint.
In the band-metal regime, the occupied bands are not separated from all unoccupied states by a gap at the chemical potential.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

At zero temperature, a conventional band metal has one or more Fermi surfaces separating occupied from unoccupied quasiparticle states in crystal-momentum space.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
