<div dir="ltr">Hello,<div><br></div><div>I strongly recommend using the atomic simulation environment (ASE) to generate surface supercells. Note that Espresso is not an approved calculator for ASE but you can still generate surfaces with ease. I typically generate the supercell, then extract the cartesian coordinates and cell parameters for Espresso. It is written in Python.</div><div><br></div><div>You can find it here:<a href="https://wiki.fysik.dtu.dk/ase/"> https://wiki.fysik.dtu.dk/ase/</a><br></div><div><br></div><div>Will DeBenedetti</div><div>Doctoral Candidate</div><div>Cornell University</div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, May 20, 2017 at 3:04 AM, Pascal Boulet <span dir="ltr"><<a href="mailto:pascal.boulet@univ-amu.fr" target="_blank">pascal.boulet@univ-amu.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">Hello,<div><br></div><div>You can try with VESTA:</div><div><a href="http://jp-minerals.org/vesta/en/" target="_blank">http://jp-minerals.org/vesta/<wbr>en/</a></div><div><br></div><div>HTH</div><div>Pascal</div><div><br><div>
