Abstract

Using the NON-EQUILIBRIUM GREEN’S FUNCTION method, the spin-dependent electron transport properties of a zigzag silicone nanoribbon are studied. In the absence of EXCHANGE FIELD, the electronic conductance can be tuned by an INHOMOGENEOUS ELECTRICAL FIELD. In this state, the nanoribbon acts as a multi-digit field effect transistor. The depositing of ferromagnetic sub layer induces EXCHANGE FIELDs in the SILICENE NANORIBBON. In addition, we use an INHOMOGENEOUS ELECTRICAL FIELD by applying external electric fields independently on the both edges of the SILICENE NANORIBBON to manipulate the spin dependent electron conductance properties. We find that complete spin polarization can take place in the presence of an inhomogeneous electric field and EXCHANGE FIELD. Here, the nanoribbon can work as a perfect spin filter. The spin direction of transmitted electrons can be easily changed by reversing the electric field direction in the edges of the SILICENE NANORIBBON. Also, in this case, the spin polarization direction can be controlled by changing the electron Fermi energy.
