Abstract
Nanoelectronics comprise the study of the electronic and magnetic properties of systems with dimensions in the nanoregime, i.e. below 100 nm. Spin electronic forms important subfield of nanoelectronics. Organic semiconductors are suitable for spin transport because of the extremely long spin-diffusion length, which stems from the weak spin-orbit coupling. In this article, the drift-diffusion transport model to evaluate the spin current in a ferromagnetic/organic semiconductor structure is studied. Effects of the spin-dependent interfacial conductance and temperature on the spin current are discussed in the existence of the electric and magnetic fields. It is obtained that the electric and magnetic fields increase the spin current significantly.
