“…Various methods have been demonstrated for the synthesis of nanocrystalline GaN, including solid-state pyrolysis of polymeric gallium amime at suitable temperatures [5,6], solvothermal reaction of GaCl 3 and Li 3 N [7,8], azidothermal reactions of GaCl 3 and NaN 3 [9], and organic chemical vapor deposition [10]. These methods usually require several steps or expensive equipment to complete the process.…”

“…Other recent synthetic methods use polymeric and single-source precursors, microwave heating, and plasma assisted nitridation. [9][10][11][12][13] Single crystals of GaN are generally grown under high temperature ͑1700-1800 K͒/ high pressure conditions ͑Ͼ2 GPa for ϳ20 h͒ since GaN decomposes at ϳ1150 K under ambient pressure. [14][15][16] Recent experiments indicate sodium fluxes can be useful for crystal growth.…”

“…The full width at half maximum of the XRD peaks shown in Fig. 2 is remarkably narrower than that of those previously synthesized by any synthesis methods for c-GaN nano-particle [4,5]. The excellent crystallinity, which is one of the merits of the Na flux method, could be demonstrated even at a low synthesis temperature of 500 o C. At 400 o C, GaN particles could not be synthesized due to phase-splitting of the Ga-Na melt.…”

“…Synthesis of not only hexagonal GaN (h-GaN), which is the stable structure in GaN crystal and is used in electronic devices, but also c-GaN nanoparticles has been reported [4,5]. However, synthesis of high-purity c-GaN remains a subject of study because mixing of the h-GaN phase in the product is inevitable.…”
