TWO-DIMENSIONAL CARBON NANOTUBE LIQUID CRYSTAL FILMS FOR WAFER-SCALE ELECTRONICS
Inventors: Michael Arnold, Katherine Jinkins, Padma Gopalan
UW researchers have now demonstrated that nanotubes collected at a liquid/liquid interface self-organize to form two-dimensional (2D) nematic liquid crystals that globally align with flow. The 2D liquid crystal assemblies are transferred and deposited onto substrates in a continuous process, generating dense arrays of nanotubes that are highly aligned, ideal for electronics. The excellent alignment and wafer-scale uniformity of the transferred assemblies enable FETs with exceptional on-state current density.

Align array carbon nanotube FETs are projected to have improved power efficiency, electrostatic gate control, and switching speed as compared to conventional semiconductors FETs
