random close packing; continuous random networks optimization covalent amorphous solids
Abstract:
We present a generally applicable method for the modeling of
covalent amorphous networks. The algorithm proceeds by
generating random close packings of anions. followed by an
optimal placement of the cations. As examples, we apply the
algorithm to a-SiO2. a-Si3N4, a-SiO3/2N1/3, and a-B2O3. (C)
