Abstract

Electron transport properties through single conjugated molecules sandwiched between two non-superconducting electrodes are studied by the use of Green's function technique. Based on the tight-binding model, we do parametric calculations to characterize the electron transport through such molecular bridges. The electron transport properties are significantly influenced by (a) the existence of localizing groups in these conjugated molecules and (b) the molecule to electrode coupling strength, and, here we focus our results in these two aspects.
