Hi, I'm trying to include e-field at Gamma for electron-phonon coupling calculations in semiconductor MoS2.
In the example file telphon_1.in, I replaced the crystal data with those corresponding to MoS2 and added:
I also use ngkpt 4 4 1 and kptopt 3 for all datasets
# DATASET 2: d/dk calculations
iscf2 -3 # Need this non-self-consistent option for d/dk
rfphon2 0 # Cancel default
rfelfd2 2 # Calculate d/dk wave function only
tolvrs2 0.0 # Cancel default for d/dk
tolwfr2 1.0d-26 # Use wave function residual criterion instead
prtwf2 1
# DATASET 3 : RF w/ electric field perturbation
getddk3 2 # d/dk wave functions from last dataset
rfelfd3 3 # Electric-field perturbation response only
there are two extra GKK files GKK13, GKK15 corresponding to e-field perturbation along direction 1 and 3.
both mrgddb, mrggkk worked fine. However, when I ran telphon_4 to compute linewidths, I got below error:
Please help! Thanks
