铝氮化物(AlN ) nanobelts 成功地通过氯化物在高产量被综合帮助蒸汽固体过程。X 光检查衍射,传播电子显微镜学,和选择区域电子衍射证明同样准备的 nanobelts 是纯的,在结构上制服和单身者水晶,并且能被索引到六角形的 wurtzite 结构。微观察在那里显示出那存在在获得的 nanobelts 的没有缺点。nanobelts 的生长方向沿着[0001 ] 。相对绝缘的常数并且绝缘的损失的频率系列在 50 Hz 的频率范围被测量到 5 MHz。这些系列的分析显示在样品的接口在样品的绝缘的行为上有大影响。作为与 AlN 微粉末相比, AlN nanobelts 有高得多的相对绝缘的常数,特别在在房间温度的低频率。
Aluminum nitride (AlN) nanobelts were successfully synthesized in high yield through a chloride assisted vapor-solid process. X-ray diffraction, transmission electron microscopy, and selected area electronic diffraction demonstrate that the as-prepared nanobelts are pure, structurally uniform and single crystalline, and can be indexed to hexagonal wurtzite structure. The micro observations show that there exist no defects in the obtained nanobelts. The growth direction of the nanobelts is along [0001]. The frequency spectra of the relative dielectric constant and of the dielectric loss were measured in the frequency range of 50 Hz to 5 MHz. Analysis of these spectra indicates that the interface in samples has great influence on the dielectric behavior of samples. As compared with AlN micropowders, AlN nanobelts have much higher relative dielectric constant, especially at low frequencies at room temperature.
