METHOD FOR GROWING SINGLE CRYSTALS

A method for growing single crystals, in particular silicon carbide single crystals, uses a device including a crucible, the crucible defining an outer surface and delimiting a receptacle having an axial extent between a bottom portion and an opening portion. The receptacle is designed for crystal g...

Beschreibung
Zusammenfassung:	A method for growing single crystals, in particular silicon carbide single crystals, uses a device including a crucible, the crucible defining an outer surface and delimiting a receptacle having an axial extent between a bottom portion and an opening portion. The receptacle is designed for crystal growth and at least one seed crystal layer is located in the opening portion, the seed crystal layer being weighed down by a weighting mass at a side remote from the receptacle and being fixed, in particular exclusively, by the weight force of the weighting mass in its position against at least one holding portion located in the opening portion.
