Paper Abstract

The miniaturization of devices and synthesis of new materials have a tremendous role in the development of powerful electronics as well as material based technologies in other areas but for the laws of quantum mechanics posing limitations besides the increasing cost and difficulties in manufacturing at such a small scale. The quest, therefore, for the alternative technologies have stimulated a surge of interest in nano-meter scale materials and devices in the recent years. Metallic nano wires are the most attractive materials because of their unique properties having myriad applications like interconnects for nano-electronics, magnetic devices, chemical and biosensors, where as the hollow tubules are equally considered to be candidate for more potent applications- both in physical as well as biosciences. Materials' processing for nano-structured devices is indispensable to their rational design. The technique, known as "Template Synthesis", using electrochemical/electro less deposition is one of the most important processes for manufacturing nano/micro structures, nano-composites and devices and is relatively inexpensive and simple. The technique involves in using membranes- ion crafted ones (popularly known as Particle Track-Etch Membranes or Nuclear Track Filters), alumite substrate membranes, besides other types of membranes as templates. The parameters viz., diameter as well as length i.e., the aspect ratio, shape and wall surface traits in these membranes are controllable. In the present work, a detailed review of this technique, synthesis of nano/micro materials including hybrid materials and devices like field-ion emitters, resonant tunneling diodes (RTDs) etc. will be presented including most of the results obtained in our laboratory.
