Abstract

Experimental investigations on thermal, thermocapillary and forced convection in Czochralski crystal growth configuration J. Aleksic', J. A. Szymczyk', A. Leder^, T.A. Kowalewski^ Department of Thermofluiddynamics and Turbomachines, Fachhochschule Stralsund (University of Applied Sciences), Germany j Department of Fluid Mechanics, Rostock University, Germany Institute of Fundamental Technological Research, Polish Academy of Sciences, Poland 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
