If the k-point mesh you selected covers the typical energy peaks of the valence band maximum (VBM or the HOMO in your description) depends on the shape of Brillouin zone (BZ) of your system. You should try to plot the band structure and assess the VBM and find out its k-point location. If the k-point mesh you selected does not cover the k-point, then the VBM peak will not contribute to your DOS plot. 敬具 西館 best regards [email protected] [email protected]
