  A structural study is presented of ab-initio molecular dynamics simulations
of Ge-As-Se calcogenide glasses performed at the same mean coordination number
but differing stoichiometry ranging between Se rich and Se poor glasses.
Starting configurations are generated via Reverse Monte Carlo (RMC) simulations
of Extended X-ray Absorption Fine Structure (EXAFS) measurements of
experimental samples. Structural analysis is presented illustrating the bonding
trends found with changing stoichiometry.
