Tetrahedrally Coordinated Random-Network Structure

Abstract

A computer study of a tetrahedrally coordinated random-network structure is reported as a model for amorphous Si or Ge. A previous model is refined to produce equal near-neighbor distances; it is more carefully statistically characterized and the coordinates of each individual atom are now known. The radial distribution function has been obtained to greater precision and to a greater radial distance; it compares well with experiment.
