Abstract:
A method for forming dielectric nano-thin films on single walled carbon nanotubes, and a method for printing a thin film transistor(TFT) using the single walled carbon nanotubes coated with such dielectric nano-thin films are provided to obtain TFT with excellent charge mobility and on/off ratio, and greatly reduce thickness of an insulation film since it is not necessary to separately prepare an insulation layer during the fabrication of the TFT. A method for fabricating single walled carbon nanotubes coated with a dielectric polymer comprises: a first step of preparing an aqueous dispersion containing single walled carbon nanotubes and a surfactant; a second step of adding a monomer of a dielectric polymer into the aqueous dispersion to stir the monomer with the aqueous dispersion; and a third step of polymerizing the monomer. The monomer is at least one selected from styrene, methyl methacrylate, acrylate, alpha-olefin, vinyl chloride, propylene, and tetrafluoroethylene. The surfactant is at least one anionic surfactant selected from sulfonate-based surfactants, fulfate-based surfactants, phosphite-based surfactants, and dithiocarbonate-based surfactants. Single walled carbon nanotubes are coated with a thin film of a dielectric polymer with a thickness of 1 to 10 nm. A single walled carbon nanotube ink is coated with a thin film of a dielectric polymer with a thickness of 1 to 10 nm. A thin film transistor(TFT) comprises a semiconductor layer formed using the single walled carbon nanotube ink. The TFT comprises: a substrate; drain electrodes and source electrodes printed on an upper part of the substrate; a semiconductor layer in which the ink is printed on upper parts of the drain electrodes and source electrodes; and a gate electrode printed on an upper part of the semiconductor layer.
