摘要：

In this investigation, a facile method to synthesize 1-D ZnO nanorod having different aspect ratio by varying the hydrothermal temperature was demonstrated. The hydrothermal reaction temperatures were optimized to obtain high aspect ratio ZnO nanorods with well-defined 1-D structures. The aspect ratio depended electron transport properties, charge recombination, chemical capacitance, life-time and charge diffusion length of 1-D ZnO nanostructures were investigated. It was observed a clear correlation between the aspect ratio and the electron transport properties of ZnO nanorods. The highest aspect ratio of 7.6 was obtained for the ZnO nanorods synthesized at 100-120 degrees C and was found to have the highest electron transport properties. It was demonstrated the formation of highly crystalline, high-aspect ratio 1-D ZnO nanorods with enhanced electron transport properties at low hydrothermal temperatures which will be beneficial for device applications.
