利用带式超高压装置,在约500 atm的条件下,采用Na通量法成功合成了纳米级立方氮化镓颗粒。在超高压装置中密封约500 atm的高压氮气,使加压的氮气在500℃下无需压缩机即可溶解成Ga-Na熔体。相比之下,传统的Na通量法是在氮气瓶的最大压力150atm下进行的。本文所用方法的一个特征是高压反应气体溶解在超高压装置内的助熔剂中。该方法制备的c-GaN纳米颗粒具有优异的结晶度和较低的六边形氮化镓混合率,解决了c-GaN合成中的两个常见问题。
Nano-scale cubic-GaN particles were successfully synthesized using the Na flux method under about 500 atm with a belt-type ultra-high pressure apparatus. High pressure nitrogen gas of about 500 atm was sealed in the ultra-high pressure apparatus, which enabled the dissolution of pressurized nitrogen gas into a Ga-Na melt at 500°C without a compressor. In contrast, the conventional Na flux method is carried out under a pressure of 150 atm, the maximum pressure of a nitrogen gas cylinder. A characteristic feature of the process used herein is that the high-pressure reaction gas is dissolved into a flux within the ultra-high pressure apparatus. The c-GaN nanoparticles obtained by this method show excellent crystallinity and a low mixing ratio of hexagonal-GaN, and thus the method solves two common problems in the synthesis of c-GaN.
