SMALL‐Hysteresis Thin‐Film Transistors Achieved by Facile Dip‐Coating of Nanotube/Polymer Composite

Abstract

Small-hysteresis, high-performance thin-film transistors (TFTs) are readily realized simply by dip-coating of a solution-processable composite. The composite consists of single-walled carbon nanotubes (SWCNTs) embedded in semiconducting polymer used as the channel material. The resultant TFTs simultaneously exhibit large on/off current ratio, high on-current level, high mobility in the range 10-20 cm(2)V(-1)s(-1), and good uniformity and scalability.
