[Pw_forum] Relax Calculation for ZnO

[Angga Fauzi]

Dear all QE users,

I am trying to run relax calculation for my ZnO system. There are something I want to ask.
	1. In running relax calculation, what occupations should I use? I am trying to use occupations = 'tetrahedra', but it doesn't work. I am afraid if I use occupations = 'smearing', my result calculation doesn't valid since ZnO is a semiconductor, not a metal.

	2. After my relax calculation is done, should I run a scf calculation again with atomic positions I get from relax calculation?
I also attach my input file. Thank you very much for your attention.

Regards,
Angga
