Crystal structures VASP Phonopy supercell>phonon dispersion https://atztogo.github.io/phonopy/ In physics,a phonon is a collective excitation in a 16 periodic,elastic arrangement of atoms or molecules in 14 condensed matter.It represents an excited state in the 12 quantum mechanical quantization of the modes of 10 vibrations of elastic structures of interacting particles. The phonon dispersion curves are calculated along 6 several lines of high symmetry,and only the phonon frequency density of states are required rather the dispersion curves.
