Carbon nanotube-based thin-film transistors on plastic film

Among various kinds of semiconductor materials, carbon nanotubes can provide high-mobility, low-operation voltage, flexible devices on plastic films at low cost. High-mobility thin-film transistors (TFTs) and functional integrated circuits (ICs) have been fabricated by simple transfer process on a transparent plastic substrate. All-carbon ICs have also been realized for the first time, which has better transparency, flexibility, and stretchability. We also demonstrate high-throughput printing fabrication of high-mobility TFT arrays with flexographic printing technique.
