One major challenge in much of nanotechnology is how to connect nanocomponents together. Despite significant advancements in nanowire growth techniques, establishment of electrical contacts to nanowire assemblies through non-destructive methods has not yet been successfully realized. Researchers now report a novel approach toward connecting and electrically contacting vertically aligned nanowire arrays using conductive nanoparticles.
Carbon nanotubes have been used as nanoreactors in a simple thermal reaction process for the fabrication of high-quality, large-yield single-crystalline magnesium nitride nanowires. These nanowires are homogeneously sheathed over the entire lengths with very thin graphitic carbon tubular layers, which effectively prevent the decomposition in the presence of water in the atmosphere.
One-dimensional nanostructures such as nanowires, in particular semiconductor nanowires, have unique applications in the fabrication of nanoscale devices. How to control the growth of semiconductor nanowires is one of the most challenging issues presently faced by synthesis chemists.
Fabrication of nanowires arrays with different patterns and separations is a major concern of the nanowire community. For this purpose, a catalyst template, which is usually a metal nanoparticle array, is needed to guide the nanowire growth.
With an increased focus on alternative sources of cheap, abundant, clean energy, solar cells are receiving lots of attention. The dye sensitized solar cell (DSSC) is one of the most important developments in photovoltaics in the last two decades. Researchers are now on the brink of improving the efficiency of DSSC through nanowires.
