We study the transport of alkali-metal ions in oxide glasses at low temperature under electron irradiation in connection with the onset of percolation through structurally relaxed SiO2 units. The relaxation of the SiO2 units forming a path for cation motion and the obtained low value for the critical exponent governing the ion diffusion coefficient are discussed.

Abstract
We study the transport of alkali-metal ions in oxide glasses at low temperature under electron irradiation in connection with the onset of percolation through structurally relaxed SiO2 units. The relaxation of the SiO2 units forming a path for cation motion and the obtained low value for the critical exponent governing the ion diffusion coefficient are discussed.File in questo prodotto:
