| 中文摘要 | GaN single crystals were successfully obtained by using Li3GaN2 flux at 800 degrees C under a nitrogen pressure of 2 atm, providing direct experimental evidence for GaN crystals grown from melts in Li-Ga-N ternary system. Then, a temperature-modulated process was introduced to grow GaN single-crystal by Li3N flux at the temperature range from 800 degrees C to T-1 (T-1 = 820, 810, and 794 degrees C). It is found that this process suppresses the negative effect of homogeneous nucleations distinctly and results in a more uniform size-distribution of GaN crystals in comparison with that grown under no modulated conditions; 800-810 degrees C is a suitable modulating region and about 68 wt % of crystals has a size larger than I mm. The layered growth mechanism is also assured by the micro-observation on crystal morphology. These results indicate a potential route for growing large GaN crystals by optimizing the modulating conditions. |
