Patent ID: 8106430

Claim:
A thin film transistor (TFT) comprising: a channel fabricated as a first layer of a composite ink mixture comprising metallic carbon nanotubes (m-NTs) and semiconductor carbon nanotubes (s-NTs) applied to a substrate, wherein the m-NTs dominate the characteristics of the composite ink mixture and are de-activated in-situ to render the channel a semiconductor channel layer; a gate area fabricated by applying a dielectric layer over a portion of the semiconductor channel layer while exposing a source area and a drain area on the semiconductor channel layer; and a gate electrode, a source electrode and a drain electrode fabricated as electrode layers of the composite ink mixture respectively applied to the gate area, the source area, and the drain area, wherein the m-NTs of the composite ink mixture of the electrode layers are not de-activated thus rendering the electrode layers of the composite ink mixture substantially conductive, and wherein a conductivity of the channel is modulated in response to a voltage applied to the gate electrode.
