The low voltage conductance of interacting two 1,4-dithiolbenzene (DTB) molecules is investigated. The simulation results show that the electron transport can be controlled either by changing the Fermi level position E{sub f} or modifying its inter-molecular spacing d. Molecular assembly system with close interaction between DTB units, affects significantly the conductance. In addition, the position of the Fermi plays an important role in determining the current flow. Moreover, it is important to note that E{sub f} affects not only the threshold voltage V{sub th}, but also the saturation voltage V{sub sat}. When E{sub f} approaches the LUMO energy level, V{sub th} decreases, while V{sub sat} increases. To conclude, the threshold voltage and the saturation voltage depend on the Fermi level position and the inter-molecular spacing.
