vaspparser.dft.waves.dos.Dos#

class vaspparser.dft.waves.dos.Dos(n_bins=100, es_obj=None, eigenvalues=None, bin_density=None)[source]#

Bases: object

The DOS class stores all information to store and retrieve the total and resolved density of states from an electronic structure calculation.

Parameters:

  • n_bins (int) – Number of histogram bins required to calculate the DOS

  • es_obj (vaspparser.dft.waves.electronic.ElectronicStructure) – The electronic structure instance for which the DOS has to be computed

  • eigenvalues (list/numpy.ndarray) – If es_obj is None, the eigenvalues could be specified as a list

__init__(n_bins=100, es_obj=None, eigenvalues=None, bin_density=None)[source]#
