Error when reading Mobility CB Fermi level

Post by plasmon »

Dear EPW developers and users,

Recently I used EPW 5.4.1 to calculate the mobility of 2D WSi2N4. When I performed the mobility calculation after obtaining the electron-phonon matrix elements, EPW can not read the Mobility CB Fermi level correctly. The output information is listed below. Could you please tell me how to fix this problem? Thank you very much!

With best regards
Hao Zhang

-----------
Valence band maximum = 15.245544 eV

Temperature 300.000 K
Mobility VB Fermi level = 15.375048 eV
Mobility CB Fermi level = 0.000000 eV

Temperature 500.000 K
Mobility VB Fermi level = 15.470404 eV
Mobility CB Fermi level = 0.000000 eV
