I calculated phonon by quantum espresso and plotted via xmgrace, my graph exhibits kink corners instead of smooth. What will be the consequence?
From the plot, it seems that you have calculated your phonon bands only "AT" the high-symmetry points, and not along a path between them.
Can you upload the scripts you used for the calculations?
I hope this helps,
Roberto
