Models of Ion Mixing,

Abstract

The phenomenon of ion mixing has many facets which are not as yet well, fully, and accurately described in theory. Radiation enhanced diffusion (RED) is a description of the transport in terms of standard diffusion greatly enhanced by the increased concentration of defects (with respect to thermally generated defect concentrations) which are necessary for diffusion to occur. Radiation induced segregation is an extension of RED which emphasizes the gradient in the defect concentration and the particular boundary conditions tht accompany ion irradiation. Both models predict a dependence on temperature in high damage rate regimes. The models are most important at high temperatures (> 20 degrees).
