Abstract

A modification of the Czochralski growth system consisting of a circular disk attached to the pulling rod has been used during the shouldering of Bi12SiO20 single crystals. Experimental results show significant changes to the melt-crystal interface shape and faceting behavior from the use of disks of different materials. A simple mathematical analysis of enclosure radiation provides a self-consistent explanation for the observed changes in terms of system thermal gradients and the intensity of melt convection.
