EFIELD = [real] 

Description: EFIELD controls the magnitude of the applied electric force field.


It is possible to apply an external electrostatic field in slab, or molecular calculations. Presently only a single value can be supplied and the field is applied in the direction selected by IDIPOL=1-4. The electric force field is supplied in units of eV/Å. Dipole corrections to the potential (LDIPOL=.TRUE.) can and should be turned on to avoid interactions between the periodically repeated images.

Mind: The electric field is defined opposite to the common definition. So electrons will move along the direction of the electric field.
