Abstract

We investigate the transport properties of a graphene nanoribbon with a tilted p-n junction. The conductance versus the Fermi energy shows step structures when the tilt angle is small. For the large tilt angles, the conductance oscillates rapidly with the tilt angle increasing, and the conductance decays non-monotonically with the longitudinal length of the p-n junction area. Based on the subband analysis, we explain these effects by the mix and the interference between different subbands of the ribbon. [ABSTRACT FROM AUTHOR]
