Since the first report on trumpet-like Zn3P2 nanowires one-dimensional 1-D nanostructures of II-V group semiconductors have attracted great research attention recently because these special 1-D nanostructures may find applications in fabricating new electronic and optoelectronic nanoscale devices. This article covers the 1-D II-V semiconducting nanostructures that have been synthesized till now focusing on nanotubes nanowires nanobelts and special nanostructures like heterostructured nanowires. Novel electronic and optoelectronic devices built on 1-D II-V semiconducting nanostructures will also be discussed which include metal-insulator-semiconductor field-effect transistors metal-semiconductor field-effect transistors and p-n heterojunction photodiode. We intent to provide the readers a brief account of these exciting research activities. Keywords Nanowires Nanotubes Nanobelts Semiconductors Nanoelectronics Introduction Because of the ability to synthesize them in numerous configurations and their unique physical chemical optical G.
