Description:
<jats:title>Abstract</jats:title><jats:p>The effect of mutual displacement of crucible and crystal or melt level change on crystallization rate is described in one‐dimensional heat‐transfer approximation. It is found that Czochralski growth system is very sensitive to mechanical instability and crystallization rate follows the jitter pattern. As an example crystallization rate behaviour is examined for fluorite and silicon crystal growth.</jats:p>
