I want to do band structure calculation of Magnesium silicide for GGA in VASP. Can anyone please help how to do this by setting initial INCAR tags and KPOINTS file? Thanks!

I assume your structure is relaxed.

  • The 1st step: self-consistent calculation to obtain converged charge density (uniform K mesh).

  • The 2nd step: non-self-consistent calculation to obtain the eigenvalue along a high symmetry path by reading previous converged charge density.

PS: you can generate the high symmetry path with VASPKIT.

Hope it helps.

First, the lattice optimization is performed, and then the atomic position is optimized. After the stable position is obtained, the static calculation can be performed, and then the k-point path is set to obtain the energy band.
