The ionic thermoelectric power of a superionic conductor is calculated using a lattice gas model in one dimension for the case where the lattice sites are 50% occupied. The calculated thermoelectric power is inversely proportional to the absolute temperature and the activation energy for ionic conduction is equal to the heat of transport. The results explain experiments fairly good.read more

A model for the heat of transport in ionic conductors
Sachi Taniguchi,Masaru Aniya +1 more
TL;DR: In this article, a model for the heat of transport in ionic conductors has been proposed based on a lattice dynamical theory of diffusion, and the authors have shown that the relationship between Q and E a is determined by the participation degree of different phonon modes, in particular the short wavelength phonons to the atomic jump processes.

Ionic transport in super ionic conductors: a theoretical model
M.J. Rice,W.L. Roth +1 more
TL;DR: In this paper, a theoretical model for ionic transport phenomena in such super ionic conductors is presented based on the hypothesis that there exists in the ionic conductor an energy gap ϵ0 above which ions of mass M, belonging to the conducting species, can be thermally excited from localized ionic states to free-ion like states in which an ion propagates throughout the solid with a velocity vm and energy ϵ m = 1 2 M v m 2.

Disorder and ionic polarons in solid electrolytes
W.J. Pardee,Gerald D. Mahan +1 more
TL;DR: In this article, the role of ion-ion repulsion and ion-phonon coupling in superionic conduction is explored and it is argued that the order-disorder phase transition is not associated with the conductivity discontinuity, but with a higher temperature second order phase transition which has been seen in some superionic conductors and which is predicted for others.
