Transport propreties of organic single electron transistor; dependence on acene length

In this work, we have studied the transport properties of the single molecule transistor using Atomistix ToolKit (ATK) simulators. We have applied the extended Huckeltheory (EHT) coupled with non-equilibrium green's function (NEGF) formalism. We have investigated the rings number effect of three polycyclic aromatic hydrocarbons (PAHs) on the transport properties. In addition, we have confirmed that our device operates as a Molecular Single Electron Transistor. The presence of Coulomb blockade phenomena has been also outlined.
