LPHON_DISPERSION
LPHON_DISPERSION = .TRUE. | .FALSE.
| Default: LPHON_DISPERSION | = .FALSE. |
Description: LPHON_DISPERSION requests the calculation of the phonon dispersion along the q-point path supplied in file QPOINTS (same format as KPOINTS).
After the computation of the force constants using finite differences (IBRION=5,6) or density-functional perturbation theory (IBRION=7,8) on a supercell it is possible to compute the phonon dispersion for the equivalent primitive cell determined by VASP by setting LPHON_DISPERSION=.TRUE.
| Mind: Only available as of VASP 6.3.2. |
