SWCNT thin film device. (a) Schematic of a SWCNT film device with standard Hall bar configuration. The yellow area represents Au (100Â nm)/Ti (5Â nm) films. The Au/Ti films have a higher sheet conductance than the gated SWCNT films, and only the Au/Ti films are considered as electrodes here. (b) Optical microscopy image of the SWCNT film device (Metal sample). (c) AFM (topography) image of the SWCNT film (Metal sample).
