A study is presented into the structural details of ab initio molecular dynamics simulations of GeAsSe chalcogenide glasses with ideal stoichiometry over a range of mean coordination numbers (MCN). The structural variability dependence upon initial starting structure, robustness of the 8-N rule and trends in the dominant bonding environments are investigated and compared to recently published models.
