Abstract

When the excitations described by the `bond lattice' model, and its `defect' model relatives, are allowed to interact, this simple class of model predicts the possibility of first-order transitions between viscous and fluid liquid states. Looking for support of this prediction, the behavior of a series of `tetrahedral' liquids, all of which are famous for one or another aspect of their behavior, was examined. It is shown that when diffusivity data for these liquids, SiO2, BeF2, water, and liquid Si, are plotted on a reduced temperature scale with glass transition temperature as the scaling temperature, a systematic pattern is revealed in which a mild deviation, in the case of BeF2, from the `strong' extreme of the normal strong/fragile glass-former pattern.
