Numerical modelling of heat transfer in GaSb Czochralski crystal growth (CZ and LEC)

By the hand of a system-oriented steady-state model of the GaSb crystal growth (CZ and LEC) the crystal-melt interface, the heat losses due to cooling, and the required crucible temperatures are calculated as a response to the boundary conditions for temperature and heat flows, and to the chosen geometry. Of special interest is a phantom of an after-heater influencing the cooling of the crystal.
