ABSTRACT
In this talk, we study problems that occur in
Czochralski growth, which is the most important
industrial method to grow semiconductor bulk
crystals from the melt. In particular, magnetic
fields, radiative heat transfer, free boundaries,
turbulence, and a very complicated geometry make
the mathematical modeling and simulation a
"grand challenge". We report advances (both
mathematical and technical) that have been made
in Berlin in the last years.
