<div dir="ltr">Consider also that the paper you mention shows the potential in eV units, whereas QE output is in Ry. <div>If you look at the energy window spanned by the potential, in the paper it ranges from about (very rough estimates) -12 to about 3 eV, ~15 eV in total, whereas your potential ranges from -0.9 to 0.3 Ry, for a total of 1.2 Ry, ~16 eV in total, maybe a careful calculation would show a closer match between the two.<div>Another term of comparison, is the difference between top and bottom constant values, reported to be 1.207 eV in the paper. Your calculation shows something like ~0.1 Ry => 1.36 eV, again not that different (and with a better estimation that can be done using the data).</div><div><br></div><div>Giovanni<br><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><span style="color:rgb(0,0,0)">-- <br><br>Giovanni Cantele, PhD<br>CNR-SPIN<br>c/o Dipartimento di Fisica<br>Universita' di Napoli "Federico II"<br>Complesso Universitario M.

<br>
Can you please explain what should be wrong? You have the same number of minima, the relative depths seem to match. The absolut position is not important but only relative energies.<br>

Subject: [QE-users] wrong plane average electrostatic potential. !! Sorry, I forgot to upload the files in the first message.<br>
<br>
Dear QE users and depeveloper:<br>
<br>
I am trying to reproduce the planar average electrostatic potential of In2Se3, as in figure 3B of the article <a href="https://www.frontiersin.org/articles/10.3389/fchem.2023.1278370/full" rel="noreferrer" target="_blank">https://www.frontiersin.org/articles/10.3389/fchem.2023.1278370/full</a>, but I get a wrong result. Attached are the input files and the graph I get.<br>
<br>
I don't know if the error is due to my input, or some software bug.<br>
<br>
Can someone tell me if I am doing something wrong?<br>
