<p>Dear QE users and developpers,</p>
<p>I'm studying the electronic structure of a system with a substitutional impurity. I observe new bands due to the impurity itself, and other bands getting shifted. The latter ones come essentially from states centered on the atoms surrounding the impurity. </p>
<p>I suspect that this is only an electrostatic effect and nothing fancy happens, but to push further the analysis I would like to quantify the total (i.e. due to electrons + ions) electrostatic potential on the impurity site and its neighbours and to compare it with the perfect crystal.</p>
<p>Can pp or any other post-processing tool provide this information?</p>
<p>I have the impression that running pp with one among plot_num==1, 2, or 11 can make what I want, but I'm confused about their meaning and use. What are the differences between these functionalities? Is it possible to use them to get the potential in a specific site of the crystal?</p>
<p>Many many thanks!</p>
<p>Cheers</p>
