<DIV> In VASP, after a relax calculation, one should run a scf calculation to get the effective charge density, which is necessary for DOS and Band-Structure calculations.</DIV>

<DIV><BR></DIV>> Dear all QE users, <BR>> <BR>> I am trying to run relax calculation for my ZnO system. There are <BR>> something I want to ask. <BR>> 1. In running relax calculation, what occupations should I use? I am <BR>> trying to use occupations = 'tetrahedra', but it doesn't work. I am <BR>> afraid if I use occupations = 'smearing', my result calculation doesn't <BR>> valid since ZnO is a semiconductor, not a metal. <BR><BR> For semiconductor occupations=fixed<BR>> <BR>> 2. After my relax calculation is done, should I run a scf calculation <BR>> again with atomic positions I get from relax calculation? <BR> <BR> For what?<BR> <BR>> I also attach my input file. Thank you very much for your attention. <BR>> <BR>> Regards, <BR>> Angga <BR>> <BR>> Angga Dito Fauzi <BR>> Undergraduate Student <BR>> Department of Physics, Faculty of Mathematics and Natural Sciences <BR>> Universitas Indonesia, Depok 16424, Indonesia <BR>> Phone: +628124139348 <BR>> Email: angga_dito_fauzi@yahoo.com <BR>> -- <BR>> This message has been scanned for viruses and <BR>> dangerous content by MailScanner, and is <BR>> believed to be clean. <BR>> <BR>> _______________________________________________ <BR>> Pw_forum mailing list <BR>> Pw_forum@pwscf.org <BR>> http://pwscf.org/mailman/listinfo/pw_forum <BR><BR>-- <BR>This message has been scanned for viruses and <BR>dangerous content by <A href="http://www.mailscanner.info/"><B>MailScanner</B></A>, and is <BR>believed to be clean.
