RADIAL TEMPERATURE DISTRIBUTION IN LINBO3 CRYSTALS PULLED BY THE CZOCHRALSKI TECHNIQUE

The influence of the ambient temperature and different thermal conduct ivities for axial and radial directions on the radial temperature diff erence distribution along the crystal axis was investigated. It was fo und that radial temperature difference distribution, which is a measur e of curvature of the thermal held, is strongly affected by Blot numbe r, and ambient temperature. The strong influence on the temperature di stribution in growing crystal has temperature gradient in the vicinity of the interface.
