Query: Comparative analysis of different preparation methods of chalcogenide
  glasses: Molecular dynamics structure simulations   Two different preparation methods (liquid-quenching and evaporation) of
chalcogenide glasses have been investigated by molecular dynamics simulations.
Our particular aim was to determine how the structural changes occur due to the
different preparation methods. We applied a classical empirical three-body
potential of selenium to describe the interactions between atoms.
  Our simulation shows that a significant difference can be observed in the
homogeneities.
