ABSTRACT
Nanoscale zinc oxide’s (ZnO’s) exceptional properties have drawn researchers’ interests in its design and nano-fabrication by precise alteration of the morphological nanostructures. Formation of one-dimensional (1-D) ZnO nanostructures in the form of nanorods and nanowires has been reported using various methods in order to harvest the unique properties of ZnO. It is well known that physical methods enable more precision in its fabrication, but the high operational cost remains the biggest drawback. Therefore, in this chapter, the progress, perspective and future outlook of 1-D ZnO nanostructures are discussed followed by their applications. Chemical fabrication methods will not only lower the fabrication cost but also enable large-scale fabrication. As lightweight wearable devices are becoming a trend, chemical fabrication methods will also offer an alternative route for 1-D ZnO nanostructures to be deposited on flexible substrates that usually possess low thermal stability.
