Figure 8: Typical structure of SWCNT-TFT. (a) Schematic diagram 1 [51]. This type of TFT is fabricated on silicon wafer. The silicon substrate works as the backgate and SiO2 works as the gate dielectric. (b) Schematic diagram 2 [52]. The other type of TFT is fabricated on flexible substrate like polyamide. (c) SEM image of a TFT fabricated on silicon substrate with SWCNT network as its channel [51].
