We fabricated polymer-laminated, transparent, all-carbon-nanotube field-effect transistors (CNT-FETs), making use of the flexible yet robust nature of single-walled carbon nanotubes (SWNTs). All components of the FET (active channel, electrodes, dielectric layer, and substrate) consist of carbon-based materials. The use of a plastic substrate that is considerably thinner than those used in other flexible CNT-FETs allowed our devices to be highly deformable without degradation of electrical properties. Using this approach, flexible, transparent CNT-FET devices able to withstand a 1 mm bending radius were realized.
