(a) Silicon back-gate (open circles, and ) and local-gate (black dots, and ) transfer characteristics in air. (b) characteristic in both sweep directions. (c) Schematic band diagram for the situations (i) and (ii) of (b) corresponding to the conventional hole current in the on state and to the BTB tunneling current, respectively. The dashed areas correspond to the source and drain regions, the light gray areas to the sections of the nanotube controlled by the back-gate and the dark-gray area to the central section of the nanotube controlled by .
