Crystal growth

Process for the production of monocrystals.

In this process, only one nucleus may be active, which is either supplied (seed crystal) or by only allowing one nucleus to grow. In general, the growth front (s. Solidification front) must remain stable, i.e. it must be controlled in a slow and continuous manner (e.g. by means of a temperature gradient which is maintained by a certain furnace layout).

Typical examples of crystal growth are the Bridgeman method (crystal growth in a pointed crucible), the Czochralski method (growth from a crucible) and so-called zone melting (growth without crucible).
