Using a low temperature hydrothermal synthesis method,ZnO nanorod networks have been directly grown across trenched Au microelectrodes arrays,which were modified with a layer of ZnO seeds.The charac-teristics of the current-voltage(I-V) and the photoresponse were obtained both in the dark and under ultraviolet illumination.The bridged nanorod network demonstrated a highly sensitive response to UV illumination in atmo-sphere at room temperature.It can be useful for nanoscale optoelectronic applications,serving as chemical sensors,biological sensors,and switching devices.
