    摘要: Techniques for selective placement of carbon nanotubes using bifunctional acid monolayers are provided. In one aspect, a method for selective placement of carbon nanotubes on a metal oxide surface includes the steps of: dispersing poly-fluorene polymer-wrapped carbon nanotubes in an organic solvent; creating a patterned monolayer of a bifunctional acid on the metal oxide surface, wherein the bifunctional acid comprises a first acid functional group for binding to the metal oxide surface, and a second acid functional group for binding to the poly-fluorene polymer-wrapped carbon nanotubes; and contacting the poly-fluorene polymer-wrapped carbon nanotubes dispersed in the organic solvent with the patterned monolayer of the bifunctional acid on the metal oxide surface to selectively place the carbon nanotubes on the metal oxide surface via the patterned monolayer of the bifunctional acid. A carbon nanotube-based device and method of formation thereof are also provided.
