Figure 5: Simulation of the suspended graphene device.

(a) Schematic view of charge carrier configuration at the unipolar point (V_left,V_right)=(−15,−10) V is indicated by a blue square in d. (b) Calculated charge carrier profile at this point and (c) associated simulated transmission function versus incident angle θ. (d) Conductance map obtained by tight-binding transport calculation as a function of V_left and V_right. (e–g) Same as a–c but for parameters at the bipolar point (V_left,V_right)=(−15,2) V is indicated by a green square in d.
