Additionally it has been shown that a macroscopic radial non-uniformity can result from flow conditions under which the solute boundary layer does not remain embedded within a momentum boundary layer flow characterised by the rotating crystal.

To this end it is likely that the process will be modified from a strictly batch process to a semi-continuous one where the melt is continuously replenished. This is not as straightforward as it may sound, one serious problem being the build up of impur

What Constitutes Whistleblowing?,The elegant, but deceptively complex, technique of pulling single crystals from a melt by first dipping a seed crystal into that melt has been developed over the last forty years to become the dominant technique for the production of bulk single crystals of a wide range of materials for the electronics and electro-optic industries.
