TWO WAYS BY WHICH SELF ASSEMBLY MAY BE USED TO PRODUCE MAGENTIC NANOWIRES

Introduction

The process of forming an ordered aggregate by a set of constituents or components spontaneously through their global energy minimization is called self assembly (Ali, 2005; Robinson, 2003).  One of the recent demands and challenges in today's world is the development of nano-circuits and devices. These circuits can be formed by nano-electronic components and the connectors used between these components. For these connectors nanowires may be used and with this increases the demand of fabricating nanowires using different techniques (Saif et al. 2003). The following section describes how self assembly is utilized to produce magnetic nanowires.

Conclusion

In the first technique, a simple and different idea has been established to create self assembled perpendicular arrays of single crystal ferromagnetic Fe nanowires with the help of spontaneous phase decomposition of a complex oxide. While the second technique, represents a method which fabricates nanowires on Silicon substrate but without the use of lithography.
