Use of Free Energy Diagrams to Interpret Ion Beam Mixing Data,
Abstract
The interpretation of ion mixing results involves the combination of thermodynamic and kinetic concepts. The use of thermodynamic concepts implies that local regions in the vicinity of a cascade achieve some form of metastable equilibrium during the relaxation period following prompt cascade events. This implies that within these local regions, certain thermodynamic variables have well defined averages (e.g., temperature, composition, etc.) while other variables (e.g. long range order) are constrained to assume non-equilibrium values by the kinetic restrictions imposed during the relaxation process following the prompt cascade events. In order to describe the metastable thermodynamics, one can use free energy diagrams. (Author)
