摘要:
Methods for fabrication of copper delafossite materials include a low temperature sol-gel process for synthesizing CuBO2 powders, and a pulsed laser deposition (PLD) process for forming thin films of CuBO2, using targets made of the CuBO2 powders. The CuBO2 thin films are optically transparent p-type semiconductor oxide thin films. Devices with CuBO2 thin films include p-type transparent thin film transistors (TTFT) comprising thin film CuBO2, as a channel layer and thin film solar cells with CuBO2 p-layers. Solid state dye sensitized solar cells (SS-DSSC) comprising CuBO2 in various forms, including “core-shell” and “nano-couple” particles, and methods of manufacture, are also described.

A method for patterning a magnetic thin film on a substrate includes: providing a pattern about the magnetic thin film, with selective regions of the pattern permitting penetration of energized ions of one or more elements. Energized ions are generated with sufficient energy to penetrate selective regions and a portion of the magnetic thin film adjacent the selective regions. The substrate is placed to receive the energized ions. The portion of the magnetic thin film is subjected to thermal excitation. The portions of the magnetic thin film are rendered to exhibit a magnetic property different than selective other portions. A method for patterning a magnetic media with a magnetic thin film on both sides of the media is also disclosed.

A method for defining magnetic domains in a magnetic thin film on a substrate, includes: coating the magnetic thin film with a resist; patterning the resist, wherein areas of the magnetic thin film are substantially uncovered; and exposing the magnetic thin film to a plasma, wherein plasma ions penetrate the substantially uncovered areas of the magnetic thin film, rendering the substantially uncovered areas non-magnetic.

This invention provides an optically transparent conductive layer with a desirable combination of low electrical sheet resistance and good optical transparency. The conductive layer comprises a multiplicity of magnetic nanowires in a plane, the nanowires being aligned roughly (1) parallel to each other and (2) with the long axes of the nanowires in the plane of the layer, the nanowires further being configured to provide a plurality of continuous conductive pathways, and wherein the density of the multiplicity of magnetic nanowires allows for substantial optical transparency of the conductive layer. Furthermore, the conductive layer can include an optically transparent continuous conductive film, wherein the multiplicity of magnetic nanowires are electrically connected to the continuous conductive film. A method of forming the conductive layer on a substrate includes: depositing a multiplicity of magnetic conductive nanowires on the substrate and applying a magnetic field to form the nanowires into a plurality of conductive pathways parallel to the surface of the substrate.

摘要:
A method of forming a solar cell incorporating a compound semiconductor is provided. The compound semiconductor is generally of the “II/VI” variety, and is formed by depositing one or more group II elements in a vapor deposition process, and then contacting the deposited layer with a liquid bath of the group VI elements. The liquid bath may comprise a pure element or a mixture of elements. The contacting is performed under a non-reactive atmosphere, or vacuum, and any fugitive vapors may be captured by a cold trap and recycled. The substrate may be subsequently annealed to remove any excess of the group VI elements, which may be similarly recycled.
