LWRITE_UNK = .TRUE. | .FALSE.
Default: LWRITE_UNK = .FALSE. 

Description: LWRITE_UNK decides whether the cell-periodic part of the relevant Bloch functions is written.


For LWRITE_UNK=True, VASP writes the cell-periodic part of the Kohn–Sham orbitals in spin channel s at k point p to the file wannier90.UNKp.s. This file can be used to plot Wannier orbitals with WANNIER90.

For details on the execution of wannier_setup in VASP, see the description of the LWANNIER90 tag. For information on the wannier90.win file and the execution of WANNIER90, we refer to the WANNIER90 manual.
