Patent ID: 8541843

Claim:
An integrated nanotube device comprising: an insulating substrate; at least one field effect transistor on the insulating substrate, the at least one field effect transistor comprising: a patterned nanotube fabric, being substantially free of metallic nanotubes and having a plurality of semiconducting nanotubes, the patterned nanotube fabric having a source region and a drain region, wherein the source region and drain region are in a spaced relation relative to one another and wherein the spaced relation defines a channel region in the patterned nanotube fabric; a gate element electrically coupled to the channel region, wherein the gate element modulates the conductivity of the channel region such that a conductive pathway is formed or unformed between the source and drain in response to electrical stimulus; wherein the at least one field effect transistor is a p-type field effect transistor; and wherein the at least one field effect transistor has the gate element embedded in the insulating substrate.
