Characterization of the graphene Hall elements with Ti/Au 1D edge contacts. (a) Output Hall voltage as a function of perpendicular magnetic field strength at 293 K and 75 K. (b) Output Hall voltage as a function of time at different applied magnetic fields at 293 K and (c) 75 K. Measurements are shown at a bias current of 90 μA and the background voltage offset is subtracted from the data.
