Abstract

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.
