I am confused about the size of the supercell as I am not
clear what is the role of this MULT. <span style="font-weight:bold">Equivalent atoms mean here
?</span>. I would be glad if you can
ellaborate this term more. I created 1*1*1 supercell (Complete file is attached with pure structure file). I got 6 Ca atoms with
total of 9 positions. <span style="font-weight:bold">I want to dope 25% Mg by replacing Ca atom.</span>
Kindly suggest how can I precisely get a least supercell to complete my
job. <br>I tried 1*1*1, 2*2*2, 3*3*3 etc supercells but the output
structure file is same. Why is it so ?<br clear="none"><br clear="none"></div><div style="color:rgb(0,0,0);font-size:18.6667px;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;background-color:transparent;font-style:normal">
