Abstract

We demonstrate a low-voltage and less hysteresis operation of single-walled carbon nanotube thin film transistors (SWCNT-TFTs) using an ionic liquid gate dielectric layer. We fabricated the density controlled SWCNT-TFTs using the inkjet printing technique, where both source/drain electrodes and the semiconducting transistor channel were made from SWCNT films. As the gate dielectric, we have adopted a printable ionic liquid for future all-printable processes and achieved marked improvements in operating voltages and hysteretic response.
