Multilevel Tunnelling Systems and Fractal Clustering in the Low-Temperature Mixed Alkali-Silicate Glasses
Figure 6
A 2D cartoon of the chocolate-like, ceramic-glass structure of a real glass, in which partial devitrification has occurred, with the location of its low-, two-species TS. In the randomly networked bulk of the material sit the STM-2LS, with their own concentration , whilst within and in the proximity of the incipient crystallites nest the ATS, with their own bulk concentration , each being described by (3) and (6). We expect and that in the best glasses.
