Abstract

The destruction of Landau levels of one-dimensional graphene nanoribbons in a modulated magnetic field is investigated by the Peierls tight-binding model. The partial flat subbands are transformed into oscillating parabolic subbands, and the dispersion is very sensitive to the modulation period and the field phase. The density of states, which reflects the main features of the energy bands, reveals peak spectra that are controllable through adjusting parameters of the modulated magnetic field. These spectra promise possible applications in electronic devices.
