trim_bandstructure#
- ifermi.interpolate.trim_bandstructure(energy_cutoff, band_structure)[source]#
Trim the number of bands in a band structure object based on a cutoff.
- Parameters:
energy_cutoff (
float) – An energy cutoff within which to keep the bands. If the system is metallic then the bands to keep will fall within +/- the cutoff around the Fermi level. If the system has a band gap, the bands from the VBM - energy_cutoff to CBM + energy_cutoff will be kept.band_structure (
BandStructure) – A band structure.
- Return type:
- Returns:
A trimmed band structure.
