Abstract

The present invention relates to a method for manufacturing a crystal with at least two segments, wherein adjacent segments differ by at least one characteristic. The different segments can, for example, be of different materials, or have a different doping agent. The method makes possible the manufacturing of segmented crystals with high crystal quality, and as planar joining surfaces between the individual segments as possible. This is achieved in that the segmented crystal is grown directly from the molten mass.
