[Pw_forum] additional electron in the field

[pari shok]

Hi.
intended to study of the impact of the electric field on an additional
electron in a structure.
I was wondering whether it is reasonable to just add one electron to the
structure and apply electric field.
Is there a way to put just one electron or an electron-hole in a box and
apply the field to it with QE?
I am thankful of any kind of help.
