Phonopy vibration mode
WebMay 28, 2013 · Science Vol. 319, p794 (2008) is an article on related substance Ag3CoC6N6. Fig4 of this paper provides partial vibrational free energy for Ag, Co and CN. (The discussion is on the 3rd column, 2nd para.) Assuming that they really mean the partial vibrational free energy, I would like to do similar analysis for our study. WebPhonon calculation is based on the assumption that atoms have their own equilibrium positions where forces on these atoms are zero. In addition, there is a unit cell that contains these atoms and the unit cell are repeated in the direct space, i.e., it forms a lattice.

WebPractical calculation of vibrational modes Common methods – based on Density-functional Theory – to calculate vibrational modes (via Interatomic Force Constants): • Frozen … WebThe frozen phonon method calculates the force constant matrix by displacing each atom in a unit cell and calculating the resulting forces on every other atom. Ideally, this is done for an infinite crystal, and the induced forces between atoms go to zero as the distance between the involved atoms increases.
