“…However, regarding the details on how the mechanical stress enters into the mechanism of light induced ionic transport remains to be solved. A related phenomena to that presented here is the acoustoionic and acoustoelectronic effect which has been investigated for many years [7,15]. By analyzing the data obtained there, we may extract useful information regarding the interaction between sound wave and charge carriers.…”

“…However, in β-Ag 3 SI, a well-known ionic conductor, the sound velocity increases with temperature in the temperature interval between 157 K and 360 K [6]. Although the temperature range is limited, the increase of the sound velocity with temperature is also observed in the superionic phase of AgI [15]. To the best of our knowledge, no satisfactory explanation has been given to those observations.…”

The ionic transport and the mechanical properties in solids are intimately related. However, few studies have been done to elucidate the background of that relation. With the objective to fill this gap and gain further understanding on the fundamental properties of ion conducting materials, we are studying systematically the mechanical properties of different materials. In the present study, after showing briefly our previous results obtained in crystalline materials, results regarding the relation between ionic conduction and mechanical properties in superionic glasses is presented. All these results indicate the intimate relation between the mechanical and ionic conduction. The results also indicate that the Grüneisen parameter and the Anderson–Grüneisen parameter of ionic conductors exhibit large temperature dependence and increase with temperature.
