<div dir="ltr">Yes, pwcond would be ideal for this. But is it possible to simulate electron transport in doped graphene (or doped materials in general) using pwcond? To include the dopant atoms explicitly, would require very large unit cells I believe. Is there a better way to do it in pwcond?<div><br></div><div>Thanks,<br>Sridhar</div><div>Purdue University</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 25, 2015 at 3:29 AM, Karim Elgammal <span dir="ltr"><<a href="mailto:egkarim@gmail.com" target="_blank">egkarim@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I believe that pwcond code in espresso, can do the job.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I myself, wants to do the same for graphene properly as well.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">you can check the documentation here, it is based on Landauer-Buttiker formula: <a href="http://iramis.cea.fr/Pisp/alexander.smogunov/PWCOND/pwcond.html" target="_blank">http://iramis.cea.fr/Pisp/alexander.smogunov/PWCOND/pwcond.html</a> </div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">and here is the input file parameters: <a href="http://www.quantum-espresso.org/wp-content/uploads/Doc/INPUT_PWCOND.html" target="_blank">http://www.quantum-espresso.org/wp-content/uploads/Doc/INPUT_PWCOND.html</a> </div><span class="HOEnZb"><font color="#888888"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Karim Elgammal</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">PhD student</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Materials- and Nanophysics</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">KTH</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Sweden</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div></font></span></div>
