摘要

The control of dopant segregation by accelerated crucible rotation was investigated for the vertical Bridgman growth of Ga-doped germanium crystals. The accelerated crucible rotation technique (ACRT) and the angular rotation technique (AVT) were considered. Both techniques were found effective in radial segregation control; however, ACRT generated more global mixing and thus slightly larger axial segregation. Computer simulation was also carried out for the experiments. The results were also consistent with previous simulation predictions and low-temperature transparent experiments.
