摘要

在本研究中，测定了不同气体气氛对静电纺ZnO纳米纤维表面电位分布的影响。使用扫描表面电位显微镜(SSPM)分析表面性质。所得结果证明了沿纤维方向的电学和结构性能的均匀性。通过改变纤维的表面电位分布，证实了氧化气体环境中金属氧化物中多数载流子损耗的影响。在干燥和潮湿的氮气和空气气氛中进行的测量可以阐明水蒸气对ZnO纤维性能的作用。

Surface potential measurements of a single ZnO nanofiber

In the present study determination of the impact of various gas atmospheres on the surface potential distribution of the electrospun ZnO nanofiber was carried out. Analysis of surface properties was performed using a Scanning Surface Potential Microscopy (SSPM). Obtained results proved homogeneity of the electrical and structural properties along the fiber. The effect of majority carriers depletion in metal oxides in oxidizing gas atmospheres was confirmed by changing the surface potential distribution of the fibers. Measurements performed in dry and humid atmosphere of nitrogen and air could clarify the role of water vapor on the properties of ZnO fibers.
