- 一种采用自催化模式制备带尖氮化镓锥形棒的方法,其特征在于分两步进行:第一步为采用溶胶凝胶法制备氧化镓/无定型碳混合物,操作步骤是:1)将硝酸镓固体粉末溶解到重量百分比浓度为62%的浓硝酸中,滴加饱和浓度的氨水到溶液中,使其pH值为7.5-8.2;2)将溶液加热到80℃时,缓慢添加柠檬酸固体粉末到溶液中,直到溶液呈现透明粘稠状,再持续搅拌2小时,然后停止加热,自然冷却后成为透明凝胶;3)将透明凝胶置于马弗炉中,在温度400℃下干燥15-45分钟,得到灰白色多层状粉末即为氧化镓/无定型碳混合物;第二步:用制备的氧化镓和无定型碳的混合物作为镓源,利用高温管式真空炉,在氧化铝瓷片衬底表面沉积带尖的氮化镓锥形棒,操作步骤是:1)将氧化镓和无定型碳的混合物放到氧化铝瓷舟中,并在氧化铝瓷舟上加盖氧化铝瓷片,氧化镓和无定型碳的混合物与氧化铝瓷片间的距离为2-3毫米,然后将瓷舟放到管式真空炉的中部;2)用纯度为99.9%的氨气作氮源,向管式真空炉内通入氨气,氨气的流动速率为50-70sccm;3)设定管式真空炉的温度为1000℃,升温速率为8℃/min,并在温度达到1000℃后保温5分钟,然后关闭加热器;4)在保持氨气流量的情况下自然冷却到室温,取出瓷片,瓷片衬底上一层浅黄色产物即为单晶的带尖氮化镓锥形棒。
