Abstract
In this Letter, the authors study the effects of electrostatic potential on spin-inversion properties in nano-scale graphene sheets with a single Rashba spin-orbit barrier using the transfer matrix method. The optimum values of the Rashba constant are obtained for maximum electron spin-inversion. It is found that, in the presence of electrostatic potential, perfect spin-inversion can take place for all values of the electron incident angle, whereas in the absence of electrostatic potential, perfect spin-inversion can take place only at specific values of electron incident angle. The spin-dependent electron conductance as well as the efficiency of graphene spin-inverter increase in the presence of electrostatic potential.
