[QE-users] dipfield

[Asad Mahmood]

Hi,

I have a hexagonal graphene(or any other) monolayer and I hydrogenate(or
flourinate, etc.) on the top surface only (single sided). Is there need to
use flag dipfield = .true ? What is benefit or disadvantage of using this
flag for optimization of L.C or bond length?
I am using 20 angstrom vacuum between two layers to avoid mutual influence.
