We report the lateral growth of ZnO nanowires on a ZnO:Ga/glass template. By reducing the oxygen flow ratio, it was found that we could change the growth direction of ZnO nanowires from vertical to lateral. ZnO nanowire-based photodetectors were also fabricated using the laterally grown ZnO nanowires. It was found that the detector current increased by more than 12 times upon ultraviolet illumination. It was also found that the corresponding time constant of our lateral ZnO nanowire photodetector was around 452 ms.
