Dear *Meysam Pazoki*:
Fermi energy indicate that:Below it, all the states is occupied by
electrons, whereas no electron is above it.
In my view, Fermi energy can below or above zero. And, in pseudopotential
method, the absolute value of fermi energy has no physical meaning.
If i am wrong, please point it out ：）
