Single-crystalline GaN nanowires have been synthesized on Si(111) substrates by magnetron sputtering through ammoniating the Ga2O3/Nb films at 900 °C in a quartz tube.

中文摘要：采用射频磁控溅射技术在硅衬底上制备Ga2O3/Nb薄膜，然后在900 °C下于流动的氨气中进行氨化制备GaN纳米线。

Then GaN nanostructured thin films comprised of regular hexagonal crystal grains have been successfully synthesized by ammoniating Ga2O3 films at the temperature of 850℃ for 15 rain in a quartz tube. X -ray diffraction reveals that the synthesized GaN is of a hexagonal wurtzite structure with lattice constants a =0.318 nm and c =0.518 nm.

然后将硅基Ga2O3置于管武石英炉中，在850℃的氨化温度下氨化15min后，成功制备出GaN薄膜，该薄膜由正六边形的晶粒组成。X射线衍射表明GaN具有六方纤锌矿结构，晶格常数为a=0.318nm和c=0.518nm.X射线光电子能谱的测试确定了样品中Ga-N键的形成，并且Ga和N的化学计量比为1：1。

The experimental results reveal that there is not interference phenomenon for quartz-crystal, but some strong interference apexes for micro-structure optical fibers at 575 nm.

实验结果表明，对石英晶体的探测没有发现相干现象，而在575 nm左右微结构光纤中产生了很强的干涉。
