An insulating state in which occupied and unoccupied single-particle bands are separated by an energy gap at integer filling. Mott and other correlation-driven insulators are not band insulators.

A band insulator is the material class whose occupied and unoccupied one-particle bands are separated by a gap at the relevant integer filling.
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.
A band insulator’s band structure has completely filled occupied bands separated from empty bands by an excitation gap at the chemical potential.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
