EPW Forum

To clarify, I want to calculate the electron mean free path using the EPW code. I can calculate the electron-phonon scattering rate ({tau}nk) from the self-energies and I need the electron velocity (vnk) to find the mean-free path ({tau}nk*vnk). I was searching the EPW documentation and EPW forum to ...

Hi, I want to calculate the mean free path. I can calculate the electron-phonon scattering rate from the self-energies and I need the velocity matrix to calculate the mean free path as mean-free path = scattering rate*velocity. However, I cannot find the velocity matrix in the output file. Would you ...
