Sonochemical growth of zinc oxide (ZnO) nanowires and nanowalls is a relatively new synthetic technique that allows for room ambient growth and large scale production. This synthesis technique allows for services ranging from gas sensors and UV switches. In comparison to the widely used hydrothermal method of growth at low-temperatures, the sonochemical technique is found to be advantageous from the environmental impact, scalability, process time and production cost viewpoints.;Using the sonochemical method, ZnO thin films, nanowires, and nanowalls, were synthesized. Although many applications can result from these nano-materials, we focus on ultraviolet (UV) photo-detectors and gas sensors. This method promises a mass-manufacturable process for fast and inexpensive ZnO nanowire production for practical low cost electronics, photonics and energy conversion applications.
