I would like to calculate the fat phonon bands for a chosen material (for simplicity, suppose GaAs), similarily as in Fig. 3 of reference :
This is effectively the analogue of projected band structure for phonon dispersion: information about which atoms contribute the specific modes to what degree. (Please also let me know if there's a more widely used term for this).
I was searching how to obtain such a "projected phonon-band" structure using Quantum Espresso, but I couldn't find anything. Is there a way? If not, is it possible to get at least some information regarding the atomic contributions to the phonon bands? Are there 3rd-party post-QE codes that I could use to obtain such info?
