Hi
I was also surprised to discover it. Matdyn.x prints all the projected
phononic dos in the dos files, they are the columns on the right of the
total dos.

Hello,
I was consulting the reference materials on materialsproject.org
<https://materialsproject.org/materials/mp-830/> for a
semiconductor. In the section on phonon results, they had the phonon
density of states plotted with the contributions of each type of atom
as well as the total DOS. I have calculated the DOS of a system
before using QE, but only did the total DOS of the system. Does QE
have the capability to give similar results?
Thanks,
Brad
Dear Brad,
for phonons I do not think there is any ready-made tool (but I could
be wrong). For phonon dispersions, we have implemented an online
phonon visulizer, based on the code by Henrique Miranda:
https://www.materialscloud.org/work/tools/interactivephonon
that allows you to explore graphically/interactively phonon dispersions
https://www.materialscloud.org/discover/2dstructures/details/BN
For the phonon DOS, if you have done a calculation with QE, you can at
zero cost interpolate/diagonalize the dynamical matrices on fine q
meshes, and build the DOS yourself. But maybe others have some tool
ready to use.
