Abstract: Graphene nanoribbon arrays, methods of growing graphene nanoribbon arrays, and electronic and photonic devices incorporating the graphene nanoribbon arrays are provided. The graphene nanoribbons in the arrays are formed using a seed-mediated, bottom-up, chemical vapor deposition (CVD) technique in which the (001) facet of a semiconductor substrate and the orientation of the seed particles on the substrate are used to orient the graphene nanoribbon crystals preferentially along a single [110] direction of the substrate.

Abstract: 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.

Abstract: Methods of forming films of aligned elongated nanoparticles, films made using the methods, and electronic devices, such as transistors, that incorporate the films are provided. In the methods, elongated nanoparticles floating at the surface of a liquid film are deposited onto a liquid film-adsorbing surface region of a substrate as the liquid film dissipates from the surface. The alignment and deposition of the elongated nanoparticles occurs along a contact line that is defined by the liquid film, the substrate, and either an immiscible liquid suspension of the elongated nanoparticles or air. As the liquid film dissipates, the contact line recedes across the liquid film-adsorbing surface region and elongated nanoparticles pinned at the contact line are deposited onto the surface in the form of a nanoparticle film.

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 of producing layers of patterned graphene with smooth edges are provided. The methods comprise the steps of fabricating a layer of crystalline graphene on a surface, wherein the layer of crystalline graphene has a crystallographically disordered edge, and decreasing the crystallographic disorder of the edge of the layer of crystalline graphene by heating the layer of crystalline graphene on the surface at an elevated temperature in a catalytic environment comprising carbon-containing molecules.

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.
