Abstract

A three-dimensional covalent network of N atoms possessing a fraction (nr/N) of r-fold-coordinated atoms will, in general, display percolation of rigidity at an average coordination number r=2.4-0.4(n1/N), where n1/N represents the fraction of onefold-coordinated atoms. As an example, we show how these ideas can elucidate the glass-forming region in the Ge-S-I ternary system.
