Dear all, I was wondering which approach would be better suited to describe an efield applied across a 2D system with surface normal in z direction. Judging from the docs both can be used to apply a field but I am curious if one has an advantage over the other. I further found the "gatefield" example in qe 6.2 and I am curious if that would be favorable over above.
The "goal" is to see if the band-structure/absorption spectrum modulation by an external electric field can be modeled with pwscf. Thanks in advance for you insights!
