Two CdTe crystals had been grown in microgravity during the STS‐95 mission. The growth configuration was dedicated to obtain dewetting of the crystals and to achieve high quality material. Background for the performed experiments was based on the theory of the dewetting and previous experience. The after flight characterization of the crystals has demonstrated existance of the dewetting areas of the crystals and their improved quality regarding the earth grown reference sample. The samples had been characterized by EDAX, Synchrotron X‐ray topography, Photoluminescence and Optical and IR microscopy. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
