Abstract

In this study, a self-assembled monolayer of octyltriethoxysilane was grown on ITO glass. Subsequently, a hydrothermal method was employed to grow low-density gallium (Ga)-doped zinc oxide (ZnO) nanorod structures. In this growth process, the undoped pure ZnO nanorods and ZnO nanorods doped with five different Ga concentrations were developed. After growing the nanorods, X-ray diffraction (XRD) analysis was conducted on both undoped pure ZnO and Ga-doped ZnO nanorods to observe the influence of Ga concentration on the crystalline structure of the ZnO nanorods. Additionally, scanning electron microscopy (SEM) was utilized to examine changes in the surface and cross-sectional growth of ZnO nanorods with varying Ga concentrations, thereby investigating the impact of Ga concentration on the growth of ZnO nanorods. Finally, a thin Pt film was sputtered onto the ZnO nanorod structures to assemble nanogenerators. Ultrasonic excitation was applied to develop these nanogenerators for electrical measurements, allowing us to explore the effects of metal doping on the nanorods’ electrical properties.
Ga浓度对ZnO压电纳米棒输出性能的影响
在本研究中,在ITO玻璃上生长了一层自组装的辛基三乙基氧基硅烷单层。随后,采用水热法生长低密度镓掺杂氧化锌纳米棒结构。在此生长过程中,制备了未掺杂的纯ZnO纳米棒和掺杂5种不同Ga浓度的ZnO纳米棒。生长纳米棒后,对未掺杂的纯ZnO和掺杂Ga的ZnO纳米棒进行x射线衍射(XRD)分析,观察Ga浓度对ZnO纳米棒晶体结构的影响。此外,利用扫描电子显微镜(SEM)研究了不同Ga浓度下ZnO纳米棒表面和截面生长的变化,从而研究了Ga浓度对ZnO纳米棒生长的影响。最后,在ZnO纳米棒结构上溅射一层薄薄的Pt薄膜来组装纳米发电机。超声波激发被应用于这些纳米发电机的电学测量,使我们能够探索金属掺杂对纳米棒电学性能的影响。
