We studied the dependence of the output of the piezoelectric nanogenerator (NG) on the inclining orientation of the ZnO nanowire arrays (NWAs). The oblique-aligned NWAs were grown by combing a modified oblique-angle sputtering technique for preparing the seed layer and hydrothermal growth. The piezoelectric output of the NWAs was studied by scanning the tip of an atomic force microscope along four different directions in reference to the inclining direction of the NWs. The statistical outputs were analyzed in reference to the theoretically calculated piezopotential distribution in the NWs. Our study provides in-depth understanding about the performance of NGs.
我们研究了压电纳米发电机(NG)的输出对氧化锌纳米线阵列(NWAs)倾斜方向的依赖关系。通过结合改进的斜角溅射技术制备种子层和水热生长,生长出倾斜排列的 NWAs。通过沿相对于 NWs 倾斜方向的四个不同方向扫描原子力显微镜的尖端,研究了 NWAs 的压电输出。统计输出结果参考了 NWs 中理论计算的压电势分布进行了分析。我们的研究深入了解了 NG 的性能。
