(Color online) (a) Schematic of ZnO nanowire placed on prepatterned Au electrodes after deposition. (b) Conductivity change of ZnO nanowires over time. The inset shows the scanning electron microscopy (SEM) image of the fabricated device.
(Color online) (a) Simulated oxygen distribution on the eighth day after ion milling process. (b) Illustration of curve fitting to determine the oxygen diffusion coefficient. The continuous lines represent the simulated results while the dots represent the experimental results. The geometrical parameters are extracted from the SEM images of the tested nanowires. The electron mobility is , which is from literature (Ref. 11 ).
TEM images of ZnO [(a) and (b)] nanobelts and (c) nanowire after deposition, showing the defects introduced in the volume as a result of nanofabrication.
