Electron Transport Properties of Rippled Zigzag Graphene Nanoribbon

Article Preview

Abstract:

In this paper, we present the calculated conductance of the rippled zigzag graphene nanoribbon and study the electron transport properties with different amplitude and period of the ripple. Based on the obtained results we find that, the conductance exhibits oscillation when the direction of the ripple is parallel to the direction of electronic flow and we ascribe it to the strain-induced modulated potential. For the second configure when the direction of the ripple is perpendicular to the direction of the electronic flow, we find that the conductance when energy varied around 0eV increases and then decreases with changing amplitude, for which the reason is still unknown.
