Can I take the optical properties and band structure from the same non-scf calculation using GW0 directives or do I need to do these separately?

~Thanks

Nevermind, I figured it out.

Dear Panda,

Would you mind to share with me how this is done? I would like to find out as well.

Thank you in advance.

HI, Any of you manage to get the band structure or to add Kpoints in the GW calculations?
I tried it in different ways and it never works.
Thanks

I have with small systems. With larger systems, I am able to get the phonon vibration modes, then plot the absorption energy curve, and then comparing this with experiment get the band gap energy, which can then be compared to non-GW calculations. I will write a blog post about it this weekend and send you the link.

You can try to do the bandstructrue of GW following the HSE06 or B3LYP ,maybe it works

Hi,

I need help to calculate the optical properties. I got a file called OPTIC. Also I have codes of prof. Furthmuller but I do not know what next I should do..

Thank you for help
