Abstract

In this paper, a simple quantum model is used to formed the current rate expressions for electronic transition to enhance the electronic current across the Au-pentacene interface of delocalized electronic state in Au metal electrode donor to localized electronic state in pentacene molecule acceptors state in polar solvent media. This work summarizes the current of electronic transfer from Gold Au donor to pentacene acceptor. The alignment of the energy level of Au metal and molecular in Au/pentacene interfaces are very important condition for the electronic transition processes. Many types of solvents were used polar media for the Au/pentacene interface. Au contact with pentacene has been give a better current results with 1-propanol solvents than solvents under same condition and parameters. We evaluated and investigated the effected of transition energies and potential energy on the electronic current. Moreover, the Au/pentacene show large current electron transfer with solvent has large polarity with large transition energy and low potential energy. Based on the theoretical results determined for the Au/pentacene system, the maximum current of electron transfer is computed with 1-propanol to be in the range to  cm4 s-1. Consequently, Au/pentacene devices supply best electronic current due to higher transition energy and low potential.
