The semi-infinite, one-dimensional molecular systems are connected to two electrodes and the electron-electron interaction is ignored. The system is described by a simple tight binding model. All calculations are based on the Green&#39s function and Landauer–Buttiker approach, and the electrodes are described in a wide band approximation.
