Abstract:
Systems and methods of nanomaterial transfer are described. A method of nanomaterial transfer involving fabricating a template and synthesizing nanomaterials on the template. Subsequently, the nanomaterials are transferred to a substrate by pressing the template onto the substrate. In some embodiments, the step of transferring the nanomaterials involves pressing the template onto the substrate such that the nanomaterials are embedded below a surface layer of the substrate. In some embodiments, the temperature of the plurality of nanomaterials is raised to assist the transfer of the nanomaterials to the substrate.
Abstract:
Activated gaseous species generated adjacent a carbon contaminated surface affords in-situ cleaning. A device for removing carbon contamination from a surface of the substrate includes (a) a housing defining a vacuum chamber in which the substrate is located; (b) a source of gaseous species; and (c) a source of electrons that are emitted to activate the gaseous species into activated gaseous species. The source of electrons preferably includes (i) a filament made of a material that generates thermionic electron emissions; (ii) a source of energy that is connected to the filament; and (iii) an electrode to which the emitted electrons are attracted. The device is particularly suited for photolithography systems with optic surfaces, e.g., mirrors, that are otherwise inaccessible unless the system is dismantled. A method of removing carbon contaminants from a substrate surface that is housed within a vacuum chamber is also disclosed. The method employs activated gaseous species that react with the carbon contaminants to form carbon containing gaseous byproducts.
Abstract:
Improved environmental barrier coatings and improved organic semiconductor devices employing the improved environmental barrier coatings are disclosed herein. Methods of making and using the improved coatings and devices are also described. An improved environmental barrier coating generally includes a primary barrier layer, a secondary barrier layer disposed on the primary barrier layer, and a passivation layer disposed on the secondary barrier layer. The secondary barrier layer is formed using atomic layer deposition.

Abstract:
Systems and methods for fabrication, delivery, and transfer of carbon nanotubes are provided. In accordance with some embodiments, carbon nanotubes can be grown and then transferred to a surface for carrying grown nanotubes. Grown nanotubes can be formed in a mat of nanotubes that are integrally held together on a film. Grown nanotube mats can be formed as a mat of freestanding carbon nanotubes bound to each other. A method to fabricate transferable carbon nanotubes can include providing a surface to carry carbon nanotubes, applying a removable adhesive on a surface, and locating carbon nanotubes on a surface having the removable adhesive located thereon. A device for holding carbon nanotubes can include a surface for carrying carbon nanotubes, at least one grouping of free standing carbon nanotubes, and a removable adhesive disposed generally between the surface and the at least one grouping of free standing carbon nanotubes. Other aspects, embodiments, and features are also claimed and described.
