Abstract

Inkjet printing is used to fabricate CN-TFT devices on PET substrate with 70 nm HfO₂ gate dielectric. By varying the amount of printing, effective mobility can be raised to 43 cm² V^-1 s ^-1 with on/off ratio ≥ 10⁴ for devices with channel length 160 μm. This demonstrates that inkjet printing is promising for fabrication of high-performance devices in flexible electronics.
