Cathodoluminescence characterization analysis and growth of ZnTe:Cu under Microgravity
Abstract:ZnTe:Cu crystals were successfully prepared on TG-II spacecraft by Te solvent Method. The quality of crystal growing in the microgravity is much better than those growing on the ground at the same experiment conditions. The size of crystals prepared on TG-II is larger than those prepared on the ground. Cathodoluminescence was used to measure ZnTe:Cu crystals at 5 kV、15 kV、25 kV voltages. CL mapping and spectra were conducted at different voltages. It was found the crystals growing in microgravity possess lower density of defects.
