    • One should bear in mind that the vacancies are generated as defect structures in the glassy network, that becomes frozen below the glass transition. Accordingly, their number concentration does not change with temperature (it may be slightly affected by aging effects). The situation is thus different from that in crystalline systems, where the number concentration of vacancies is in general thermally activated.

    • note
    • On one hand the short-time dynamics in the hopping model is not realistic due to the neglect of local ion rearrangements. On the other hand, the network response to an external shear field may involve a dominant characteristic length scale exceeding the mean jump distance of the ions.
