[Pw_forum] Application of electric field to quantum dot

[Parham Shenavar]

Dear all

I did charge analysis on a quantum dot using gamma point only. I want study
of charge analysis under influence of a constant electric field using
lelfield=.true. option.

1. Is it possible? I found a lot of examples that deal with k-points while
I am only using gamma point.

2. If I want field in X direction, I should set gdir=1 but how can I have a
good estimate for efield value?

3. Is it mandatory to set nberrycyc other than its default value?

Sorry if my questions are very elementary.
