<div dir="ltr">Dear all,<div><br></div><div>I am still observing something strange in my slab + dipole correction calculation that I do not fully understand.</div><div><br></div><div>When using dipfield+tefield (eopreg and emaxpos well within the vacuum region) I encounter a "saggy" electrostatic potential (plot_num=11) despite the sawtooth efield potential (plot_num=12) looking as usual. Maybe someone can give it a look and confirm if this is due to the excess charge in the system (this does not happen when running the same system in VASP)?</div><div><br></div><div>I attach input and the plot of the potential for 2 and 4 layers of vacuum (more vacuum does seem to improve the situation).</div><div><br></div><div>Thank you in advance for your time and assistance!</div><div><br></div><div>Chris <br clear="all"><div><br></div><div>PS: I am using a QE version with dipole bug fix:</div><div><br></div><div> Program PWSCF v.6.2.2 starts on 25Jun2018 at 10:39:24 <br></div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Postdoctoral Researcher<br>Center for Quantum Nanoscience, Institute for Basic Science<br>Ewha Womans University, Seoul, South Korea<blockquote type="cite" style="font-size:12.8px"><div dir="ltr"><div><div dir="ltr"></div></div></div></blockquote></div></div>
