[Pw_forum] how to get fermi energy for semiconductor in pwscf calculation

[bamidele ibrahim]

Thanks for that information. But, using occupations='smearing' , what should the smearing='???' be. also, how do i get the degauss='??' value.

You can try to use smearing in scf calculation by adding occupations='smearing' in &system namelist.

 dear all,

 I am working on some semiconductor materials, i want to plot there band structure. After running the scf,nscf and band calculations. To plot the band structure, i was asked by the plotband.x to input the value of fermi energy which i don't have. Please, kindly assist me with this problem if anybody have an idea of what to do.
