Self-assembled nanostructure nanodevices

The formation of nanostructures such as nanodot arrays has drawn a great attention due to the feasible applications in a variety of functional structures and nanodevices containing optoelectronic device, information storage, and sensing media [1-3]. The various methods such as self-assembled nanodots from solution onto substrate, strain-induced growth, and template-based methods have been proposed for the fabrication of nanodot arrays on a large area, [4-6]. However, most of these works can be applied to the small scale systems due to the limited material systems.

It is noteworthy that self-assembly of anisotropic nanostructures, such as nanorods or nanowires, into well-controlled hierarchical arrangements represents a challenge in view of the integration of such nano-objects with unique properties within functional nanodevices for optoelectronic, information storage, catalysis, etc. that are frontier areas of research in chemistry and materials science. 

Concerning nanostructured magnetic nanocomposites, a large part of the research effort in this field is oriented to the control of particle size and organization by self-assembly, block copolymers, dendrimers or liquid crystals. These methods open the possibility of an easy fabrication of nanodevices at mild conditions and they have attracted the interest of the big companies in the field. An illustrative example of research in this field can be found in the work of the magnetic materials group at NIST. ...
