Abstract :
Electronic transport in molecular devices is carefully studied, especially the interface effect, which is considered as a key factor for dominating device characteristics. Conductance of device show oscillates when the separation distance between molecule and electrodes changes. This implies that a closer contact do not always lead to a better characteristics of device, such as current-voltage (I-V) characteristics. Moreover, the effect of different size of electrodes of a more complex device is also examined.
