Molecular wires: tuning of electron transport
arXiv:0909.3708 · doi:10.1016/j.ssc.2007.10.016
Abstract
Electron transport characteristics through molecular wires are studied by using the Green's function formalism. Parametric calculations are performed based on the tight-binding model to investigate the transport properties through the wires. The transport characteristics are significantly influenced by (a) the interference effects, (b) chemical substituent group, (c) molecule-to-electrode coupling strength and (d) the gate voltage, and, here we focus our results in these aspects. In this article we also discuss the noise power of current fluctuations. The noise power gives key information about the electron correlation which is obtained by calculating the Fano factor (F) and the complete knowledge of the current fluctuations is very essential to fabricate efficient molecular devices.
