[Pw_forum] Definition of Fermi level in PWscf

[loc duong ding]

Dear all users,

I try to calculate the work function of CNTs. However, I am not clear the definition of Fermi level in PWscf code. How we can define Fermi level in case of metal and semiconductor by DFT?  

I greatly appeciate for all your helps.
