Abstract:

We study the influence of ripple waves, originating from the electromechanical effects, on band structures of graphene nanoribbons (GNRs)- GNRs are complex systems that require novel approaches for their analysis, due to multiscale and multiphysics effects involved. Here, we develop a mathematical model and we show that the externally applied magnetic fields along z-direction in combination with pseudo-fields enhance the spin splitting of GNRs bands. In particular, we show that the strain tensor induce quantum confinement effect that turn to lead the opening of the bandgaps at Dirac point- Such finite band gaps are highly sensitive to the control parameters (period length, applied stress) of the ripple waves that help to design the optoelectronic devices for straintronic and spintronic applications.
