Abstract: Methods of forming films of aligned carbon nanotubes on a substrate surface are provided. The films are deposited from carbon nanotubes that have been concentrated and confined at a two-dimensional liquid/liquid interface. The liquid/liquid interface is formed by a dispersion of organic material-coated carbon nanotubes that flows over the surface of an immiscible liquid within a flow channel. Within the interface, the carbon nanotubes self-organize via liquid crystal phenomena and globally align along the liquid flow direction. By translating the interface across the substrate, large-area, wafer-scale films of aligned carbon nanotubes can be deposited on the surface of the substrate in a continuous and scalable process.

Abstract: Methods for forming carbon nanotube arrays are provided. Also provided are the arrays formed by the methods and electronic devices that incorporate the array as active layers. The arrays are formed by flowing a fluid suspension of carbon nanotubes through a confined channel under conditions that create a velocity gradient across the flowing suspension.
