Research Abstract

Polarized Raman spectra of Agss-alumina have been measured. The interatomic potentials were determined by a non-linear least square fitting between phonon eigenvalues from Raman and dynamical matrix calculation based on a Rigid-Ion model. A molecular dynamics(MD) calculation has been carried out using the model crystal of Agss-alumina to understand the many-body effects for the fast ionic diffusion. We proposed a new insight into the super ionic conduction, that is, the activation energy for the ionic transport is composed of two kinds of elements ; a "static" activation energy and a "dynamic" one. The static activation energy is the cost of averaged energy difference in the various structural configurations at equilibrium state. The dynamic activation energy is an additional energy required for the structural relaxation induced by the jump process.
