Abstract: Electron transport characteristics through molecular wires are studied byusing the Green-s function formalism. Parametric calculations are performedbased on the tight-binding model to investigate the transport propertiesthrough the wires. The transport characteristics are significantly influencedby a the interference effects, b chemical substituent group, cmolecule-to-electrode coupling strength and d the gate voltage, and, here wefocus our results in these aspects. In this article we also discuss the noisepower of current fluctuations. The noise power gives key information about theelectron correlation which is obtained by calculating the Fano factor F andthe complete knowledge of the current fluctuations is very essential tofabricate efficient molecular devices.
