Abstract
One of the greatest technological and scientific challenges of crystal growth is to
achieve homogeneity of the material properties (e.g. electrical resistance,, in the
micro range). According to the present know-how, the cause of fluctuations of
the electrical resistance is due to fluctuations of the growth rate of the crystal.
One of the possible causes for fluctuations of the growth rate is the instationary
convection in the melt. The focus of the project is to examine the influence of the
thermal Marangoni effect on the temperature and
