SEM images of the 3D ZnO hybrid structures formed at different film growth times of: (a) 40 min and (b) 80 min.
HRTEM images of: (a) a part of the 3D ZnO hybrid structure composed of the ZnO nanowire and the thickened grains along the radial direction; (b) the filmlike structure at the top of nanowires; and (c) the ZnO nanowires. The insets are the corresponding SAED patterns.
curves showing (a) the photocurrents and darkcurrents of the ZnO film and buffer layer and (b) those of the combined 3D hybrid.
Time response of the relative conductance of the 3D hybrid structure with turning on and off the UV light in the air and nitrogen atmospheres.
