DOS and band structure

SiestaStudio can plot the electronic density of states (DOS) and band structure from standard SIESTA output files. Both can be shown separately or overlaid in a combined Band+DOS view.

Band structure

Import a .bands file from a completed SIESTA band-structure run. The plot shows energy (eV) on the y-axis and the k-path on the x-axis. High-symmetry point labels are read from the file or can be edited in the panel.

Controls:

  • Drag the Fermi energy line to adjust the zero reference.
  • Toggle spin channels (for spin-polarized calculations).
  • Set the energy window with the range sliders.

Density of states

Import a .DOS file. The total DOS is plotted as a curve. You can overlay the Fermi energy line and adjust the energy window.

Combined Band+DOS view

When you have both a .bands and a .DOS file for the same calculation, use the Combined tab to display the band structure and DOS side by side with a shared energy axis.
