Abstract
The temperature dependence of the low energy excitation (LEE) mode in cation superionic conductors is explained based upon an ionic plasma m odel. We regard the lattice ions as a uniform negative charge distribu tion and consider the LEE mode as a plasma oscillation of cations unde r the anion background. The model explains qualitatively the character istic features of the LEE mode, A comparison with the boson peak obser ved in amorphous solids is also presented.
