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. |
