Image of FIG. 1.
FIG. 1.

(a) AFM image of a single ZnO nanowire. (b) AFM section analysis showing that the diameter of the nanowire is about 110 nm. (c) The corresponding current image of the ZnO nanowire by C-AFM under the voltage of −10 V and the loading force of 20 nN. (d) The current image section analysis showing that the current through the ZnO nanowire is about 72 pA. (e) The current image under the voltage of −10 V and the loading force of 40 nN.

Image of FIG. 2.
FIG. 2.

(a) and (b) show the topography image and the corresponding current image of a single ZnO nanoneedle, respectively. (c) A plot showing the linear relationship between the measured current and the diameters of the ZnO nanoneedle.

Image of FIG. 3.
FIG. 3.

Model for current flow through the AFM tip, the ZnO nanoneedle, and the metallic graphite substrate. The equipotentials were shown in the model.

Image of FIG. 4.
FIG. 4.

(a) and (b) show the value of and the value of as a function of the diameters of the ZnO nanoneedle, respectively.
