Abstract

One-dimensional nanostructures hold the promise of becoming critical elements for next generation nanoscale electronic and photonic devices. While significant efforts have been devoted to the development of nanotube or nanowire based transistors, little has been done on their photonic counterpart. Here we summarize our recent efforts on one-dimensional crystalline nanostructures, in particular, the zinc oxide (ZnO) nanowires grown on a sapphire substrate. ZnO is a wide bandgap (3.37 eV) compound semiconductor that is especially suitable for blue and ultraviolet (UV) optoelectronic applications. Room-temperature optical energy conversion and stimulated UV light emission from ZnO nanowires are emphasized, along with a discussion of potential applications of nanoscale lasers.
