| Abstract: | Recent developments of infrared materials growth in space have been reviewed. The growth methods mentioned here includes melt, vapor growth, liquid phase epitaxy and molecular beam epitaxy. The fundamental principles have been presented for materials grown by different methods. A comparison of ground and space growth has been made giving the challenges and advantages respectively. The ZnTe:Cu crystal was grown using the melt method under microgravity conditions on board of TG-Ⅱ spacecraft, and a reference crystal was grown on Earth under gravity conditions. The related experimental results between the space and terrestrial conditions have been compared. Both the current methods of melt and vapor and perspective development by molecular beam epitaxy have been presented for high-performance, large-scale infrared material growth in space. Lastly the future direction is demonstrated for the space-borne growth of infrared material. |
