Relaxed Continuous-Random-Network Models

Abstract

Elastic-energy-relaxed 201-atom and 519-atom continuous-random-network structures are described, and $G\mathrm{}\left(r\right)\text{'}\mathrm{s}$, corrected for finite-size effects, are compared with experimental measurements on amorphous germanium. Excellent agreement is obtained for the principal peaks in $G\mathrm{}\left(r\right)\mathrm{}$. Even subtle features of $G\mathrm{}\left(r\right)\mathrm{}$ such as the shape of the second peak and structure between the second and third peaks accord remarkably well with experiment.
