| 20110048508 | Doping of Carbon Nanotube Films for the Fabrication of Transparent Electrodes - 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. | 03-03-2011 |
| 20110124187 | VAPOR PHASE DEPOSITION PROCESSES FOR DOPING SILICON - A process of doping a silicon layer with dopant atoms generally includes reacting a vapor of a dopant precursor with oxide and/or hydroxide reactive sites present on the silicon layer to form a self assembled monolayer of dopant precursor; hydrolyzing the self assembled monolayer of the dopant precursor with water vapor to form pendant hydroxyl groups on the dopant precursor; capping the self assembled monolayer with an oxide layer; and annealing the silicon layer at a temperature effective to diffuse dopant atoms from the dopant precursor into the silicon layer. Additional monolayers can be formed in a similar manner, thereby providing controlled layer-by-layer vapor phase deposition of the dopant precursor compounds for controlled doping of silicon. | 05-26-2011 |
| 20110151653 | SPIN-ON FORMULATION AND METHOD FOR STRIPPING AN ION IMPLANTED PHOTORESIST - A spin-on formulation that is useful in stripping an ion implanted photoresist is provided that includes an aqueous solution of a water soluble polymer containing at least one acidic functional group, and at least one lanthanide metal-containing oxidant. The spin-on formulation is applied to an ion implanted photoresist and baked to form a modified photoresist. The modified photoresist is soluble in aqueous, acid or organic solvents. As such one of the aforementioned solvents can be used to completely strip the ion implanted photoresist as well as any photoresist residue that may be present. A rinse step can follow the stripping of the modified photoresist. | 06-23-2011 |
