  • 摘要: The virtual absence of gravity-dependent phenomena in microgravity allows an in-depth understanding of fundamental events that are normally obscured and therefore are difficult to study quantitatively on Earth. Of particular interest is that the low-gravity environment aboard space provides a unique platform to synthesize alloys of semiconductors with homogeneous composition distributions, on both the macroscopic and microscopic scales, due to the much reduced buoyancy-driven convection. On the other hand, the easy realization of detached solidification in microgravity suppresses the formation of defects such as dislocations and twins, and thereby the crystallographic perfection is greatly increased. Moreover, the microgravity condition offers the possibilities to elucidate the liquid/solid interfacial structures, as well as clarify the microstructure evolution path of the metal alloys (or composites) during the solidification process. Motivated by these facts, growths of compound semiconductors and metal alloys were carried out under microgravity by using the drop tube, or on the scientific platforms of Tiangong-2 and SJ-10. The following illustrates the main results.
