Abstract
This paper presents experimental data on the growth of multicrystalline silicon with tailored electrical properties using starting silicon of purity better than 99.999 at %. Our calculations demonstrate that the effective distribution coefficients of Fe-group impurities decrease with increasing impurity concentration in the starting charge.
