Hi

I have a couple of questions regarding electric field.

The unit of electric field in the forum says eV/A. Shouldn't it be something like V/A?

IDIPOL sets the direction of the electric field. If I set Efield=0.1 and IDIPOL=3, the z direction will be set. If I want to reverse the direction in z, can I set Efield= -0.1?

Thanks!

If you want to reverse the direction in z, I think a quick method is to rebuild your supercell by reverse coordinates in z direction.
