Dear Dr. Kondrin,
Thank you for your answer, however I found in the forum that
If your k point grid is fine enough, if you plot lambda as a function of
the broadening there is a plateau, i.e. it looks like this:
| \______ <-- converged value
The correct value of lambda is the one on the plateau http://qe-forge.org/pipermail/pw_forum/2014-October/105303.html
And I wonder what value of broadening should be taken to get this plateau. Understand that this value must be small but how far. Could I expect that in my case the plateau at broadening ~0.2.
