Nanotransfer Printing of Organic and Carbon Nanotube Thin-Film Transistors on Plastic Substrates

摘要

A printing process for high-resolution transfer of all components for organicelectronic devices on plastic substrates has been developed and demonstratedfor pentacene (Pn), poly (3-hexylthiophene) and carbon nanotube (CNT) thin-filmtransistors (TFTs). The nanotransfer printing process allows fabrication of anentire device without exposing any component to incompatible processes and withreduced need for special chemical preparation of transfer or device substrates.Devices on plastic substrates include a Pn TFT with a saturation, field-effectmobility of 0.09 cm^2 (Vs)^-1 and on/off ratio approximately 10^4 and a CNT TFTwhich exhibits ambipolar behavior and no hysteresis.
