FIG. 1.

(a) Set of printed samples on flexible polyimide substrate. (b) Optical image of the devices. (c) Low magnification TEM picture of the MWCNTs. (d) High magnification TEM picture of the MWCNTs. The arrows indicate “bamboo-type” defects in the nanotubes structure. (e) I-V curves of devices as a function of the channel length (dots: , stars: , squares: ).

FIG. 2.

(a) Photoresponse of the device with channel length biased at 0.2 V. IR power is . (b) Photoresponse as a function of the power density of the incident radiation. (c) Responsivity of three devices as a function of the channel length and the forcing current. (d) Responsivity for a forcing current 1 mA as a function of the sensitive area and the resistance.
