Abstract

In this research, we investigate the properties of spin-dependent electrical transport in molecular nanostructures through a heterojunction molecular bridge of fullerene and pentacene molecule as electron acceptor and donor, coupled with two semi-final copper electrodes. For this purpose, the spin-dependent Hamiltonian is determined for the single strip and by using the Green's function approach in the framework of strong correlation, we obtain the dependence of the electric transport properties of the spin-orbit Rashba interaction, as well as the applied voltage on this structure. The results obtained from the calculations show that the spin polarization is up to 70% effective in controlling the spin of incident electrons. This molecular inhomogeneous nanostructure may be useful in the design of spintronic devices.
