Electron transport through molecular bridge systems.
Electron transport characteristics are investigated through some molecular chains attached with two non-superconducting electrodes by the use of Green's function method. Here we do parametric calculations based on the tight-binding formulation to characterize the electron transport through such bridge systems. The transport properties are significantly influenced by (a) the length of the molecu...
متن کاملEffect of isomers on quantum transport through molecular bridge system
Quantum transport for different models of isomer molecules attached to two semi-infinite leads is studied on the basis of Green’s function technique. Electronic transport properties are significantly affected by (a) the relative position of the atoms in these molecules and (b) the molecule-to-lead coupling strength of these molecular bridge systems.

متن کاملEffect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...
