ABSTRACT

Nanowires are structures with at least one of their dimensions in the 1-100 nm range; typically they are several microns in length with diameter under 100 nm. Growth processes must be able to preferentially support growth in one dimension. The key requirements for growing nanowires are that there must be a reversible pathway or condition near equilibrium between a uid phase such as solution, melt, or vapor and a solid phase, and also the adatoms in solid phase should have high surface or bulk mobility [1]. Nanowires have been synthesized using a variety of techniques and the present chapter aims at explaining the approaches in detail.
