Phony Definition & Meaning - Merriam-Webster

WebPhonons are quantizations of the normal modes of atomic oscillations in a crystal. We can use DFT and some post-processing software to calculate the vibrational modes of a crystal, calculate the phonon density of states, and integrate that to get the vibrational entropy, enthalpy, and heat capacity of the crystal. http://muchong.com/bbs/search.php?_f=xgztss&wd=Born%D3%D0%D0%A7%B5%E7%BA%C9%BC%C6%CB%E3
