Abstract
Official abstract text for this publication.
High density films of semiconducting single-walled carbon nanotubes having a high degree of nanotube alignment are provided. Also provided are methods of making the films and field effect transistors (FETs) that incorporate the films as conducting channel materials. The single-walled carbon nanotubes are deposited from a thin layer of organic solvent containing solubilized single-walled carbon nanotubes that is spread over the surface of an aqueous medium, inducing evaporative self-assembly upon contacting a solid substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A film comprising an array of aligned s-SWCNTs, wherein the array of aligned s-SWCNTs has a charge carrier mobility of at least 30 cm 2 V −1 s −1 and an on-off ratio of at least 6×10 3 . 2. The film of claim 1 , wherein the array of aligned s-SWCNTs has a charge carrier mobility of at least 38 cm 2 V −1 s −1 or higher. 3. The film of claim 1 , wherein the film has a semiconducting single-walled carbon nanotube purity level of at least 99.9%.
