Abstract:
Nanoelements such as single walled carbon nanotubes are assembled in three dimensions into a nanoscale template on a substrate by means of electrophoresis and dielectrophoresis at ambient temperature. The current-voltage relation indicates that strong substrate-nanotube interconnects carrying mA currents are established inside the template pores. The method is suitable for large-scale, rapid, three-dimensional assembly of 1,000,000 nanotubes per square centimeter area using mild conditions. Circuit interconnects made by the method can be used for nanoscale electronics applications.
Abstract:
A method of forming a high aspect ratio adhesive structure, the method comprising fabricating a porous template comprising at least a first tier and a second tier; introducing a softened polymer into the template; and separating the polymer from the template.
Abstract:
The invention relates to a method of forming at least one nano-structure with a reusable template structure having a channel. The method includes introducing at least one reagent into the channel, and reacting the at least one reagent to form a nano-structure within the channel. The nano-structure forming channel may be positioned in alignment with one or more electrode structures, which may be positioned within or upon the substrate, may be embedded in the reusable template structure, and/or may be external electrode structures positioned outside of the reusable template structure and independent of the substrate. In addition, the electrode structures may be a source material for the formation of the nano-structure in the channel.
Abstract:
A method and apparatus for growing nanostructures is presented. A growth substrate including at least one reaction site is provided as is a device disposed proximate the growth substrate. Energy is provided to the reaction site and a reaction species is introduced to the growth substrate. This results in a nanostructure growing from the reaction site wherein the growth process of the nanostructure is controlled by providing a force to the device.
Abstract:
A template is provided (12’) on a substrate (10) with a pattern of nanoscale pores (14) extending through to the substrate. The template (12’) may be, for example, porous anodic alumina. Self-assembling molecules (20) are then introduced to the template, such as by immersing a template in a solution (18) of these molecules. The self-assembling molecules (20) have a bonding group that will bond with the substrate. The result is that the self-assembling molecules (20), possibly after being triggered to self-assemble, assemble to form nanoscale islands in the pores. The template may be stripped from the substrate and nanoparticles (30) or biomolecules (40) may be attached to the nanoislands.
Abstract:
A piezoelectric microphone and/or a piezoelectric microphone system is presented herein. In an implementation, a piezoelectric microphone includes a microelectromechanical systems (MEMS) layer and a complementary metal-oxide-semiconductor (CMOS) layer. The MEMS layer includes at least one piezoelectric layer and a conductive layer. The conductive layer is deposited on the at least one piezoelectric layer and is associated with at least one sensing electrode. The CMOS layer is deposited on the MEMS layer. Furthermore, a cavity formed in the CMOS layer includes the at least one sensing electrode
Abstract:
A process for manufacturing micro-structured bodies made of plastics has the following steps: a) a micro-structured plate-like base body is used, the first side of which represents a first surface of reference and the second side of which is micro-structured in such a way that micro-structured bodies made of plastics project on a structure bottom, and the structure bottom and the reference surface extend parallel to each other; b) a second, micro-structured side of the base body is coated with a material; c) the surface of the base body-coating material is faced parallel to the first reference surface, forming a second reference surface; d) the base body is abraded on its first side parallel to the second reference surface at least until the structure bottom is reached, and then e) the material is selectively removed from the plastics.
