Abstract:
Devices, materials and methods for producing and integrating carbon nanotubes (CNT) into TFTs to form unipolar CNT TFTs are provided. CNT TFTs comprise doped layers between the CNT active layer and the source/drain electrodes capable of providing a carrier-trapping function such that unwanted carrier charge injection is suppressed between the electrodes allowing for the unipolar operation of CNT TFTs. Methods and apparatus for forming unipolar N- or P-type SWCNT TFTs are also provided.

Claim (Index 17):
A method for manufacturing a unipolar thin film transistor comprising one of either a bottom-gate or a top-gate process:\n wherein the bottom-gate process comprises:\n providing a substrate, \n patterning a gate electrode and dielectric layer on the substrate, \n depositing an active-layer comprised of a thin-film layer of single-walled carbon nanotubes on said dielectric layer, \n patterning at least a doped layer, and a drain and a source electrode either below or above the active-layer such that the portion of the active-layer overlapping the channel is exposed, and such that the doped layer is disposed between the drain and the source electrode and the active-layer, and \n wherein the doped layer is one of either n+ or p+ doped, such that the TFT demonstrates unipolar characteristics; and \n wherein the top-gate process comprises:\n providing a substrate; \n depositing a dielectric layer on the substrate; \n depositing an active-layer comprised of a thin-film layer of single-walled carbon nanotubes on the dielectric layer; \n patterning a gate electrode and dielectric layer on the active layer to form a channel; \n patterning at least a doped layer, and a drain and a source electrode either below or above the active-layer using a photomask and photolithography process such that the portion of the dielectric overlapping the channel is exposed; and \n wherein the doped layer is one of either n+ or p+ doped, such that the TFT demonstrates unipolar characteristics.
