Phonon modes
Posted: Tue Nov 12, 2013 3:21 pm
Hi,
I am using a 2x2x1 supercell and the primitive cell contains 12 atoms. So, the super cell contains 48 atoms. The number of phonon frequency obtained are 3N(144). Now, there are zone center phonon frequencies. Is there any way in vasp or any information in any file which can be used to identify the symmetry modes or this cant be done suing VASP?
Thanks!
