if you believe it is a semiconductor, does *NOT* use the smearing, as I told you before.
Next, the problem arise from the k-point grid, which is not uniform. Try to understand what is going on with your qe setup: cells and sampling,
in order to check it I suggest you to reduce the number of k-points and bands. (your k point sampling is extremely big!!) and set the verbosity high in order to see them. Please note that the correct syntax for the K-points is :
Code: Select all
K_POINTS {automatic}
If the setup of Yambo says you "Gamma point only" it means that something went wrong so it is useless to run GW calculations.
I do not have time to reproduce calculations now, as it does not look to me a problem of yambo, but your qe setup. Try to understand, if you does not succeed post it again, and I will try to have a look at it when I've time.
Cheers,
