Synthesis of Nanowires

Growth Mechanisms. Growth mechanisms have been investigated, andsev-eral theories have been proposed. There are two general models that are used to explain catalytic synthesis of nanowires or nanotubes. The first is called tip growth, in which... 

The variety of porous solid materials that can be used as templates for nanostructure synthesis has been reviewed by Ozin (1992). In the template-assisted synthesis of nanowires, the pores or voids of the template are filled with the chosen material using a number of approaches. Nanowires have been derived via pressure injection, electrochemical deposition, and vapor deposition, as described in the following sections.

One-dimensional (ID) nanostructures such as nanowires, nanorods and nanobelts, provide good models to investigate the dependence of electronic transport, optical, mechanical and other properties on size confinement and dimensionality. Nanowires are likely to play a crucial role as interconnects and active components in nanoscale devices. An important aspect of nanowires relates to the assembly of individual atoms into such unique ID nanostructures in a controlled fashion. Excellent chemical methods have been developed for generating zero-dimensional nanostructures (nanocrystals or quantum dots) with controlled sizes and from a wide range of materials (see earlier chapters of this book). The synthesis of nanowires with controlled composition, size, purity and crystallinity, requires a proper understanding of the nucleation and growth processes at the nanometer regime.
