WitrynaCompared to the standard CZ a lower oxygen concentration can be obtained and the impurity distribution is more homogeneous. This method offers also the possibility to produce detector grade silicon … 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.
Witrynaimaging the impurity distribution in ice cores can be refined and strongly improved. A novel cryogenic two-volume ablation chamber is paired with a rapid aerosol transfer system in order to achieve fast washout times (34 ms). In so doing, we are able to analyze ice cores for the first time using next generation LA-ICP-MS imaging … Witryna30 this new approach was transferred to ice core analysis with LA-ICP-MS, now offering to study the impurity distribution in ice cores in 2D. First results clearly demonstrated a close connection between grain boundaries and high-resolution LA-ICP-MS signals, which became particularly evident for the example of sodium (Bohleber et al., 2024).
