Hi, I have continued working on this to try and get the phonon dispersion to converge, I increased the number of q and k points to 16*16*16 and while this did improve the output it still has not reached convergence with the phonon dispersion output by ph.x. I feel like I am missing something obvious ...

Hi Sabya, Thank you for the quick response and sorry it took me so long to reply. Attached are two tar.gz files containing the input and output files for the QE phonon and EPW calculations, phonon.tar.gz and epw.tar.gz respectively. The directory epw contains a subdirectory epw_aco which contains ...

Hi EPW users, I am trying to calculate the electron phonon coupling matrix close to conduction band minimum in Si in order to calculate the acoustic deformation potential, however I have run into a problem. For a set polar angle between the electron and phonon vectors I am sweeping through a full ...
