GROWTH OF SEMICONDUCTOR CRYSTALS ON SOUNDING ROCKETS -AN EFFICIENT ALTERNATIVE TO MANNED MISSIONS

摘要

Sounding rocket experiments, providing micrograv-ity times of 6 minutes (TEXUS) or 12 minutes (MAXUS) allow the growth of bulk, elemental semiconductor materials of a length of several mm. On the other hand, long duration crystal growth experiments with low growth rates must be performed on long duration missions and cannot be done on sounding rockets.
