Impurity distribution
Witryna20 sty 2024 · Combined with Scheil equation, the impurity distribution results can be corrected. Figure 11 shows the distribution of Fe impurities in the Si-rich layer after the correction. The results show that after the application of the diffusion correction for the Fe impurity, the Fe distribution model in the silicon-rich layer is closer to the ... Witryna4 sty 2024 · The impurity distribution is the result of the parallel force balance which in the stationary form can be written as [29, 30]: Where −∇ n I T i represents the pressure gradient, S I,fr is the friction force due to the main ions, S I,th is the thermal force and eZn I ∇ II φ the electric force.
