Fig. 3

a Cross-sectional view of measurement setup, the left part is kept at constant potential, with Fermi level at CNP. Potential in the right part is varied. b BLG resistance (in log scale) color plot as a function of displacement field and charge-carrier density n. c Zoom-in view of the left side of d, corresponds to oddly gated configurations. d BLG resistance (in log scale) as a function of the top-gate potential when the bottom gate is fixed at different potentials. Peak values of curves grow linearly with increasing D-field with a straight line as a guide to the eye.
