thanks for your reply
Actually, one of individual spread was high around 14 (ang. square ) . I am doing it with changing some parameters. I will let you know, once it is done.

Dear users, I am using epw.x to examine electron phonon coupling in PbI2. already I have gone through tutorial for SiC. But for PbI2 ,as soon as the wannier part gets completed, I get an error "segmentation fault occurred " . I am giving my epw input file here. can you please help me to fi...

sir, thanks for your help, the error was there only , I was not using those flags of SOC. After that I did this calculation to calculate electron relaxation time for 2D PbI2, just after it does wannierisation part, it gives me error "segmentation fault". Basically I did a phonon calculatio...

Hi users, I was running EPW to calculate electron relaxation time for PbI2 with incorporating SOC. after it writes in output file =================================================================== irreducible q point # 1 =================================================================== Symmetries...

dear users, I am also getting the same problem for my 2d PbI2 system. and yes , my k points in nscf output file and input file are different. I tried your suggestion nosym = .true. , but It didn't work. I am giving you my epw input file. &inputepw prefix = 'pbi2' amass(1)=207.2 amass(2)=126.9044...

hi users,
I am new to this calculation. can you tell me, how do you decide values of wmax_specfun , wmin_specfun , nw_specfun , nbndskip, nbndsub, Dis_win_max and Dis_froj_min ?


thanks

dear sir, in the very begining of the calculation. I am getting this error. may I have explanation of all parameter of epw input file to calculate electron linewidth.

thank you

hi EPW users
I am new to this calculation, I am doing it to calculate electron line width for cdI2 monolayer . actually , when I am running epw.x, it's giving me error "segmentation fault". can anybody help me to get ot of it ?
