Structural relaxation in amorphous substances with highly non-equilibrium structure

Structural relaxation in amorphous substances with highly non-equilibrium s tructure produced by plasma sputtering, plasma melting, chemical deposition techniques is investigated. It is found that regularities of structural re laxation in these substances are similar to those observed in rapidly quenc hed glasses and may be described by the Tool-Narayanaswamy glass-transition model. For investigated substances, this result gives an opportunity to pr edict stability of their properties using a glass-transition model. (C) 200 0 Elsevier Science B.V. All rights reserved.
