Abstract

Nanowires of polypyrrole have exhibited switching transition that reduces the resistance of the wires by several orders of magnitude under certain bias around and below 30 K temperature. Here, we have shown that by incorporating gold in these polypyrrole nanotubes using a cost effective template based single-step chemical synthesis technique, this novel resistance switching transition could be extended beyond liquid nitrogen temperature (> 90 K) to make this phenomena technologically relevant. The single step synthesis technique, reported here, provides us uniform mixing of gold and polypyrrole during the formation of composite-nanotubes; with appropriate choice of materials, this synthesis technique can be extended to form nanotubes of other metal-polymer composites.
