A Laboratory Apparatus for Single Crystal Preparation by Czochralski Method

The rapid development of the application of semiconductors has stimulated extensive investigations of single crystal growth from a melt. Czochralski method has proved to be the most suitable for that purpose, and therefore it has been mostly studied and developed1•2• In the present communication a simple laboratory apparatus for »crystal pulling« is described. The apparatus can be used not only for growing single crystal of germanium but also of other materials with relative low melting point and convenient crystallization properties.
