• Carbon nanotubes (CNTs) and semiconductor
  nanowires have attracted much attention in recent
  years not only for their small dimensions and
  unique morphologies, but also for their potential
  applications in various technologies. Since their
  discovery in 1991 by Iijima and coworkers, carbon
  nanotubes have become one of the most popular
  materials in nanoscience and nanotechnology and
  have been investigated by many researchers all
  over the world. Many potential applications of
  carbon nanotubes and nanowires have been
  proposed, largely based on theoretical and
  experimental results, including conductive and
  high-strength composites energy storage and
  energy conversion devices sensors field
  emission displays and radiation sources hydrogen
  storage media and nanometer-sized semiconductor
  devices, probes, and interconnects.
• After more than ten years of rapid development
  promoted by a worldwide research effort, carbon
  nanotube and nanowire research has reached a
  phase in which the basic concepts have been
  explored, and the technological promises
  outlined. However, in order to fully exploit
  these promises, major breakthroughs, especially
  in the area of nanotube and nanowire materials
  science, must be achieved before the real
  technological application of carbon nanotube and
  nanowire devices can be realized. In this
  presentation, the development of carbon nanotubes
  and semiconductor nanowires including controlled
  synthesis, structural characterization,
  electronic manipulation, and potential
  applications in relation to the existing problems
  will be reviewed. A comparison of the research
  results of the authors group with those reported
  by others is discussed. The progress and
  challenges of this study will be addressed.
