To expound superconductive quantum transport for C20 fullerene with disparate electrode material

摘要

In this paper we expounded the optimal electrode material for fullerenes, being explored for the molecular electronics based applications. We scrutinized the largest curvature fullerene, C stringed to three different electrode materials viz. Copper, Silver and Gold using semi-empirical approach for this two probe modelling. We perceived that the transport phenomena for copper and silver electrodes throughout entire negative bias range were almost comparable with the similar set of response to the applied potential. However, for positive bias range, the transport phenomenon for Gold and Copper electrodes was comparable. Moreover, Silver Electrode configuration had least Conduction Gap with symmetric I-V curves. This leads to the conclusion that Silver electrodes offer more stability and linearity in its characteristics providing us with another ideal option for semiinfinite electrodes in nano world apart from Gold electrodes.
