WebThe free energy at temperature T and constant volume V is give by F(V;T) = E 0(V) + F vib(V;T) + F el(V;T); (1) 2 where E 0(V) is the ground state (T = 0K) total energy of the crystal, F vib(V;T) is the vibrational free energy which is come from the phonon contribution. In the quasiharmonic approximation F vib(V;T) is written in the form F WebApr 10, 2024 · The phonon dispersion curves and partial phonon density of states (PhDOS) were calculated by PHONOPY [28] and VASP codes according to the density functional perturbation theory (DFPT) [29]. Phonon frequencies were read from the 2nd order force constants that obtained by static calculation. ... When above the Debye temperature … WebIn Debye theory, the Debye temperature is the temperature of a crystal's highest normal mode of vibration, i.e., the highest temperature that can be achieved due to a single normal vibration. The Debye temperature is given by where h is Planck's constant, k is Boltzmann's constant, and is the Debye frequency . Debye Frequency, Debye Theory orc 2105.06
