Zg. Wang et al., ELECTRICAL-PROPERTIES OF SEMIINSULATING GAAS GROWN FROM THE MELT UNDER MICROGRAVITY CONDITIONS, Chinese Physics Letters, 13(7), 1996, pp. 553-556
A technologically important undoped semi-insulating (SI) GaAs single c
rystal was successfully grown in the Chinese recoverable satellite as
far as we know for the first time by using a similar growth configurat
ion described previously. The experimental results proved that the spa
ce SI GaAs crystals have a lower density of defects and defect-impurit
y complexes as well as a better uniformity.
