[QE-users] QE-epw erro >> Conduction band minimum

[王绍菲]

When i calculated the carrier mobility using epw2.in as the example.

I got the message like that:

      Conduction band minimum = ********** eV




    Temp [K]  Fermi [eV]  Elec density [cm^-3]  Elec mobility [cm^2/Vs]

     ===================================================================

       50.000     10.6630       0.000000E+00                NaN  x-axis
                                                            NaN  y-axis
                                                            NaN  z-axis
                                                            NaN     avg
      800.000     11.7971       0.000000E+00                NaN  x-axis
                                                            NaN  y-axis
                                                            NaN  z-axis


                                                            NaN     avg

I thought there must be some wrong in my epw2.in files. but I don't know why ?




Hoping to receive letters.




Your sincerely
