Static Electric Field

For systems without 3D periodic symmetry it is possible to specify an external electric field in the z-direction.

EField

Include a homogeneous static electric field in the z-direction:

EField
   Ez rval
   {Unit [Volt/Angstrom | a.u. | Volt/bohr | Volt/Meter]}
End

Ez This option expects a real value which is the strength of the electric field.

Unit (Default: Volt/Angstrom) This options specifies the unit of the electric field.

The static field is explicitly handled in the determination of the orbital coefficients, energy, and gradients. If you apply it to any other property, such as the NMR shielding tensor, dielectric function, solvation energy, etc., the result is probably not entirely correct. In case of doubt contact the SCM staff.
