Dear all PWSCF users,
Before I calcualte the electron-phonon coupling constant, I should judge the convergence of lambda with k-mesh and Gaussian broadening. But my results
show that lambda at a choosed q point do not close to be a constant with increasing Gaussian broadening at different k-meshs, it continues to decrease. I think the largest k-mesh has been already very large. So what is the reason for this and how should I choose the gaussian broadening in this case.
Thanks for any suggestion.
