Model Parameters

  We investigated the transient enhanced diffusion of boron at a temperature range from tex2html_wrap_inline4703 to tex2html_wrap_inline4707 . The experimental data were taken from [Sol90] [Cow90a] [Bac95]. Most of the parameters we used are well established in literature, like the diffusivity of interstitials tex2html_wrap_inline5285 , vacancies tex2html_wrap_inline5287 and the according equilibrium concentrations tex2html_wrap_inline5289 and tex2html_wrap_inline5291 (cf. [Bro87] [Tan85]). For the initialization of the point defect concentrations we used the +1-model with the same initialization factor tex2html_wrap_inline5293 for both quantities ( tex2html_wrap_inline5295 ). The model parameters are given in Table 4.3-2.
