I do not know exactly what you mean by electrostatic potential map, but I<br>
think this is something you can do with pp.x after the pw.x calculation is<br>
finished. Have a look at PP/Doc/INPUT_PP.html (it takes 10 minutes to read it)<br>
and you'll have an idea of the quantities you can plot (the total and hartree<br>
potentials among them) and how you can plot them (i.e. you can plot a plane<br>
inside the unit cell). Please come back to us if there is any detail you<br>
cannot understand.<br>
<br>
hth, kind regards<br>
