Abstract:
A nanowire device and a method of making a nanowire device are provided. The device includes a plurality of nanowires functionalized with different functionalizing compounds. The method includes functionalizing the nanowires with a functionalizing compound, dispersing the nanowires in a polar or semi-polar solvent, aligning the nanowires on a substrate such that longitudinal axes of the nanowires are oriented about perpendicular to a major surface of the substrate, and fixing the nanowires to the substrate.
Abstract:
A nanowire includes an electrically conductive catalyst nanoparticle first portion, a semiconductor wire second portion, a first dielectric shell around the first portion, and a second dielectric shell or functionalization around the second portion. A material of the second dielectric shell or functionalization is different from a material of the first shell.
Abstract:
A method for transferring an assembly of oriented nanowires from a liquid interface onto a surface including providing a first liquid and a second liquid, wherein the first and second liquids phase separate into a bottom phase, a top phase and an interface between the bottom phase and the top phase, providing nanowires in the first and second liquids such that the majority of the nanowires are located at the interface and providing the nanowires onto a substrate such that a majority of the nanowires are aligned with respect to each other on the substrate.
Abstract:
A method of fabrication of an ordered nanowire film comprising the steps of: adding nanowires to a liquid comprising a solvent, wherein each nanowire has a first end and a second opposite end, and a character which is different adjacent to the first end from adjacent to the second end; providing the liquid on a substrate; thinning the liquid into a film; positioning nanowires in the liquid film such that they are affected, based on said character, to be oriented in a predetermined direction with respect to a surface of the film; removing the solvent from the liquid film, such that the nanowires are moved into aligned position closer to each other by capillary force or surface tension; and solidifying the liquid film to a solid film. The invention also includes an apparatus for carrying out the method.
