    摘要： The present invention provides a method for selectively placing carbon nanotubes on a substrate surface by using functionalized carbon nanotubes having an organic compound that is covalently bonded to such carbon nanotubes. The organic compound comprises at least two functional groups, the first of which is capable of forming covalent bonds with carbon nanotubes, and the second of which is capable of selectively bonding metal oxides. Such functionalized carbon nanotubes are contacted with a substrate surface that has at least one portion containing a metal oxide. The second functional group of the organic compound selectively bonds to the metal oxide, so as to selectively place the functionalized carbon nanotubes on the at least one portion of the substrate surface that comprises the metal oxide.

    摘要： A photosensitive monolayer is self-assembled on an oxide surface. The chemical compound of the photosensitive monolayer has three components. A first end group provides covalent bonds with the oxide surface for self assembly on the oxide surface. A photosensitive group that dissociates upon exposure to ultraviolet radiation is linked to the first end group. A second end group linked to the photosensitive group provides hydrophobicity. Upon exposure to the ultraviolet radiation, the dissociated photosensitive group is cleaved and forms a hydrophilic derivative in the exposed region, rendering the exposed region hydrophilic. Carbon nanotubes or nanocrystals applied in an aqueous dispersion are selectively attracted to the hydrophilic exposed region to from electrostatic bonding with the hydrophilic surface of the cleaved photosensitive group.

    摘要： The invention is directed to a method of forming carbon nanomaterials or semiconductor nanomaterials. The method comprises providing a substrate and attaching a molecular precursor to the substrate. The molecular precursor includes a surface binding group for attachment to the substrate and a binding group for attachment of metal-containing species. The metal-containing species is selected from a metal cation, metal compound, or metal or metal-oxide nanoparticle to form a metallized molecular precursor. The metallized molecular precursor is then subjected to a heat treatment to provide a catalytic site from which the carbon nanomaterials or semiconductor nanomaterials form. The heating of the metallized molecular precursor is conducted under conditions suitable for chemical vapor deposition of the carbon nanomaterials or semiconductor nanomaterials.

    摘要： A semiconductor device and a method of fabricating a semiconductor device are disclosed. Embodiments of the invention use a photosensitive self-assembled monolayer to pattern the surface of a substrate into hydrophilic and hydrophobic regions, and an aqueous (or alcohol) solution of a dopant compound is deposited on the substrate surface. The dopant compound only adheres on the hydrophilic regions. After deposition, the substrate is coated with a very thin layer of oxide to cap the compounds, and the substrate is annealed at high temperatures to diffuse the dopant atoms into the silicon and to activate the dopant. In one embodiment, the method comprises providing a semiconductor substrate including an oxide surface, patterning said surface into hydrophobic and hydrophilic regions, depositing a compound including a dopant on the substrate, wherein the dopant adheres to the hydrophilic region, and diffusing the dopant into the oxide surface of the substrate.

    摘要： Techniques for increasing conductivity of carbon nanotube films are provided. In one aspect, a method for increasing conductivity of a carbon nanotube film includes the following steps. The carbon nanotube film is formed from a mixture of metallic and semiconducting carbon nanotubes. The carbon nanotubes are exposed to a solution comprising a one-electron oxidant configured to dope the semiconducting carbon nanotubes to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The step of forming the carbon nanotube film can be performed prior to the step of exposing the carbon nanotubes to the one-electron oxidant solution. Alternatively, the step of exposing the carbon nanotubes to the one-electron oxidant solution can be performed prior to the step of forming the carbon nanotube film. A method of fabricating a transparent electrode on a photovoltaic device from a carbon nanotube film is also provided.
