High Current-Induced Electron Redistribution in a CVD-Grown Graphene Wide Constriction

Figure 2

(a) The resistance () from = −2.5 to 2.5 T through the CVD graphene wide constriction as a function of magnetic field at = 1 K. Inset shows the WL fitting from = 0 to 2.5 T (red line) at = 1 K for magnetoconductance (normalized by ) of the wide constricted CVD graphene device. (b) The periodic resistance oscillations after eliminating the WL peak and averaging background at = 1 K. The inset shows the Fourier spectrum of the resistance oscillations at = 1 K with the Lorentz fitting (red line) for periodic magnetic field interval = 0.49 T.
