Recent works have demonstrated that carbon nanotube thin-film transistors (CNT TFTs) have excellent mechanical flexibility and stretching ability. However, they still exhibited a degradation of drain current with applied strain. Another issue to be addressed is high-voltage (a few ten V) operation due to the polymer-based gate dielectric which is flexible and stretchable, but of low-dielectric constant. Here, we have realized low-voltage operable and highly-stretchable all-carbon CNT TFTs by introducing a novel local strain control structure.
