[QE-users] energy band

[Neelam Swarnkar]

Dear expert and all

I have done bands calculation , or fermi energy is -0.1382 Ry .
but not received energy bands above this fermi energy , only received bands
till -0.18 Ry energy .

so, how can I calculate the above energy bands in my DFT calculation? I am
using qe-6.3 .

input file also attached.
&control
    calculation = 'bands',
    prefix = 'Dope-Zn4Sb3_exc1',
    outdir = './tmp/'
    pseudo_dir = './'
    verbosity = 'high'
