Abstract
The wall free growth of CdTe by the Bridgman technique under microgravity was performed. This phenomenon called Detached or Dewetting growth was studied in the flight mission STS- 95. At this mission two CdTe crystals were grown co-doped with vanadium and zinc. Identical samples were grown with different ampoule designs. The effect of Detached or Dewetting growth was observed by analysis of crystal surface and roughness by optical and mechanical methods. All results of the crystals grown under microgravity are compared to the earth grown reference samples. Surface differences can be found between the (mu) g and the 1g samples. The surface roughness measurements demonstrate that the detaching was partially successful.
